Infrastructure Is Done, People Are the Bottleneck: Data Notes from a Second-Floor Table Tennis Centre

There is an office building in Keighley, in the north of England, that you would not bother turning your head for if you walked past it on an ordinary afternoon. Grey facade. Discreet signage. Glass doors reflecting the streetlights. You would walk on, thinking of something else.

But up on the second floor, behind that unremarkable door, are eight table tennis tables arranged in a row. Each table is individually enclosed with surrounds and netting. There is a kitchen area. There is a refreshment area. And there is a separate meeting room, not a cafe corner but a proper classroom, with desks and chairs and a board.

Eight tables. That is the first number I held onto when I read Table Tennis England's internal bulletin about this centre.

But the way those eight tables are organised is what made me stop. Each table has its own perimeter. Balls do not fly onto the neighbouring table. The bounce of each ball sounds distinct, one beat at a time. For someone who has spent hours in halls where three or four tables are crammed into one space, this is a luxury of organisation, not of money.

The number knows how to hold its breath, and I wait for it to exhale.

A story about foundations, not about peaks

Let me be clear from the start: this is not the story of a world championship. There are no stars. There are no medals. There is no match worth quoting a scoreline from.

This is a story about foundations. And in my experience, it is stories about foundations that decide the future of a sport over the next ten years.

In Vietnam, when people talk about developing grassroots table tennis, the first question is usually: do we have a venue, do we have tables, do we have money for rackets. Infrastructure is always the first bottleneck. But the story from Keighley runs in the opposite direction. There, infrastructure is solved. And once infrastructure is good enough, the question shifts elsewhere: who will coach, how will they coach, and how long will they stay.

The Keighley centre sits on the second floor of an office building. From the outside, by all accounts, nothing suggests a table tennis hall inside. This is the kind of venue that in Saigon I like to call "hidden in the market". You only know it exists if someone guides you there.

Inside, around eight tables. A kitchen and refreshment area. A separate classroom. This configuration allows the centre to play, teach and host events, all in the same space, without moving.

I once worked as a data consultant for a club in Ho Chi Minh City, and I know the value of this kind of configuration. When theory and practice can run back-to-back in the same building, coaching costs fall and coaching quality rises, because learners can apply what they have just been taught at the table.

That is why I believe those eight tables are not just eight tables. They are a coaching platform.

A chain of data evidence

When I opened the bulletin and rearranged the details, I found a chain of five events, ordered by importance.

First, Steve Brunskill, a Coach Developer at Table Tennis England, visited Keighley. Steve's role is not to inspect facilities but to help the club plan for the "people" side of the sport. It is a small detail that carries a lot of information: the national governing body is going down to club level to help build a coaching workforce, rather than sitting above and issuing regulations.

Second, part of a Level 1, or Coaching Assistant, course was delivered at Keighley itself. Ten learners took part, coming from a range of backgrounds, in both playing level and coaching experience. Ten people. A small number. But notable because it shows that demand for coach education in this area is real, not speculative.

Third, a CPD session, that is Continuing Professional Development, dedicated to serving technique is being planned, again with Steve Brunskill's support. This is the point I held onto longest. It shows two things. One: the governing body treats serving as a key technical area that grassroots coaches need to upgrade. Two: they are not training coaches once and walking away, but building a continuous learning pathway.

Why serving? Because serving is the first technique of every point, and also the technique grassroots coaches are most likely to teach incorrectly. Choosing serving as a coach-education topic shows an understanding of where the sport needs intervention.

Fourth, Table Tennis England announced a new coaching membership programme, effective from the 2026/27 season. Alongside it comes a Coach Plus tier, a membership level receiving additional support from the organisation's Coach Development Team. This is a structurally important detail, because it turns coach education from a one-off transaction into a long-term relationship.

Fifth, Andy Bray, who oversees and supports the centre's development, is described as having proactively arranged coaching qualifications and CPD opportunities. Steve described Andy as enthusiastic, always wanting to move the club forward. One of Andy's priorities is to build a new group of coaches.

But here is the crux: Andy works abroad for significant periods.

The crowd will read this and think: ah, a dynamic club, a dedicated leader. But I stop somewhere else. If the key leader is frequently absent, what keeps the club running day to day?

That is a question the bulletin does not answer. And unanswered questions are often where the truth lives.

Three layers of data stacked on each other

When I combined those five events, I saw three layers of problems.

The first layer is infrastructure. This layer is solved. Eight tables, a classroom, a refreshment area. The club has enough space to play, teach and host events. This is a solid foundation.

The second layer is the coaching workforce. This layer is being built. The Level 1 course with ten learners, the serving CPD session, the coaching membership programme for 2026/27. This is the layer receiving the heaviest investment, and the one the governing body is targeting.

The third layer, the deepest and least discussed, is the sustainability of people. A leader who works abroad. A new group of coaches not yet formed. A CPD session still in the planning stage. This is the layer where data is still thin, and by my own principle, where data is thin, judgement must be cautious.

But it is precisely that thinness that points to something: the bottleneck is no longer money or tables. The bottleneck is finding someone patient enough to keep the fire burning every day.

Let me illustrate with a personal experience. In 2026, when I was still a data consultant for a club in Ho Chi Minh City, my team went on a winning run that the media attributed to fighting spirit. I opened the data table and saw the opponent's PPDA was just 8.2, meaning they deliberately dropped pressing to counter-attack. That winning run, by actual xG, was 4.7 goals below the goals scored. In other words, the results looked better than the underlying performance.

The crowd reads the scoreline. I read the gap between result and process.

With Keighley, that gap sits here: professional facilities, but a thin coaching workforce. A centre with its own classroom, eight individually enclosed tables, able to run theory and practice back-to-back, has the potential to become a regional coach-education hub. But potential is not achievement.

An old recording is a mirror, and only those who dare to look will see themselves.

When premium infrastructure becomes pressure

I want to go deeper into a paradox few people notice.

Good facilities can be a burden, not just an asset. Because they create expectations. When you have eight individually enclosed tables, people expect coaching quality to match. If the coaching workforce does not keep up, the hall will be judged lower than an ordinary hall with a good coach.

In other words: premium infrastructure sets a higher output standard. That is pressure, not just opportunity.

I have seen this in football. A club builds a new stadium, beautiful and modern, then loses several home games in a row, and the fans turn away. The beautiful stadium does not save the team. On the contrary, it makes defeat more painful.

With Keighley, a similar risk exists at a smaller scale. If the new group of coaches is not built in time, those eight tables will be a beautiful room with players, but without teachers. And then the quality of the player experience will fall, even though the facilities have not changed at all.

This is why I consider Andy Bray's priority of building a new group of coaches the most correctly directed decision in the whole story.

Noise and signal: a comparison with the transfer window

During the transfer window, my phone is full of rumours. Player X moves to club Y. A fee of Z million. Everyone talks, everyone debates. But when I sit down with the data table, I usually ask a different question: where does that money go, and does it create long-term value?

Most transfer noise is about unverified numbers. Signing fees for free agents, as I have analysed before, can be even more toxic than transfer fees, because they slip past the core scrutiny of financial regulations. Yet the crowd is still swept along by the glamorous figures.

The Keighley story is a signal in the opposite sense. It is not glamorous. It sits inside an internal bulletin few people read. But it shows a table tennis nation investing in exactly the right place: people.

In table tennis as in football, people tend to invest in what can be seen. Grounds. Equipment. Prize money. Things that photograph well and make the news easily. But what decides long-term quality is what cannot be seen: who coaches, how they coach, how much they are paid, how long they stay.

As someone who has worked with data, I recognise this pattern. Clubs pour money into goalscoring forwards, but what decides results is defensive structure and pressing systems. The flashy is always remembered, the foundation always forgotten.

At Keighley, the coaching membership programme for the 2026/27 season is precisely an effort aimed at the foundation. That is why I rate it highly on strategy, even though I cannot yet rate it on results. It shifts the focus from how many tables to how many coaches are supported.

Every number is a puzzle piece, but I do not assemble them out of habit.

The habit is to look at eight tables and see prosperity. I look at the ten learners of the Level 1 course and ask: how many of them will still be coaching in three years?

The blank cells in the data table

Here, I want to step away from the conventional reading.

Conventionally, a bulletin about a grassroots club like this would be read as a positive story: an impressive facility, an enthusiastic leader, a bright future. Not wrong. But if we stop there, we miss the most important part.

The first thing the bulletin does not say: the club's current number of coaches. There is no figure. That means we cannot assess the actual speed of expansion, only the ambition.

The second thing the bulletin does not say: the centre's financial model. Rent on the second floor of an office building is not cheap. Maintaining eight tables, netting, surrounds and a refreshment area is not cheap either. No funding source is mentioned. This is a large information gap.

The third thing the bulletin does not say: coach retention rate. This is the perennial problem of the volunteer sector, where people complete a qualification and then leave, because coaching work does not pay enough to live on. The new membership programme for 2026/27, with the Coach Plus tier, may be an attempt to address exactly this problem. But how it operates, free, paid or discounted, is not stated.

The crowd looks at the pretty picture. I look at the blank cells in the data table.

There is another small detail worth noting: the centre's location. Sitting on the second floor of an office building whose exterior does not reveal its purpose, the centre depends on active promotion for people to know it exists. This is a weakness in discoverability, to use the analyst's term. A good facility that is hard to find may fail to convert quality into participation volume.

I have followed matches at national youth events, and what I learned is this: never judge a table tennis nation by its medal count. Judge it by the number of coaches trained each year. Medals are the result. Coaches are the process.

Why this small story is worth reading

Someone will ask: why analyse a grassroots club in England, when Vietnamese table tennis has so much to do?

Because big signals always come from small places. And because how a sport treats its grassroots layer will decide its elite layer over the next ten years.

In England, they are pouring money into the process. They have a Coach Developer visiting clubs. They have qualification courses delivered on site. They have a CPD session dedicated to serving. They have a membership programme for coaches. This is a systematic chain of investment, not scattered actions.

And the good part is that they start from small clubs. Not from the national team. Not from a national training centre. But from a hall on the second floor of an office building in Keighley.

This is a lesson I think Vietnamese table tennis can take note of. We usually start from the top down: national team, championships, medals. But the foundation lies below, in grassroots clubs, in the people who teach table tennis to children at weekends.

If we do not invest in that layer, the upper layer will forever lack a source.

A note on the number ten

I return to the number ten, the learners in the Level 1 course.

In data analysis, sample size matters. Ten people is a small sample. No strong statistical conclusion can be drawn from it. But in the context of club development, ten people is a signal.

Ten people means at least ten individuals in this area are interested in becoming coaches. Not one, but ten. That shows demand exists and can be expanded.

The next question is: how many of those ten will continue with the serving CPD? How many will sign up for coaching membership for 2026/27? How many will still be coaching in three years?

These are questions the current data does not answer. But they are the indicators I will be watching.

The crowd looks at the scoreline, I look at the forgotten pass.

In this case, the forgotten pass is the number ten. Not the eight tables. But the ten people.

Takeaway

My data cafe is busiest when the ground is empty.

At Keighley, the ground is not empty. It is full of players, with classes and courses. But the emptiness that needs filling does not sit within the four walls of the hall. It sits at the human level, in finding and keeping coaches who still want to be on court after the certificate has been handed over.

I will be watching Table Tennis England's coaching membership programme for 2026/27 as an indicator. If it keeps the grassroots coaching cohort in place, that is a signal applicable anywhere. If not, those eight tables will just be a beautiful room, with players, but without teachers.

And for a sport still finding its way like Vietnamese table tennis, that signal is worth waiting for. Not waiting for a win. But waiting for another number to appear: the number of coaches still around after the first season.

When that day comes, I will once again open the data table and wait for the number to breathe.
