The Empty Data Cells Hiding Vietnam's Young Table Tennis Talent

In a small hall in Ho Chi Minh City, I open a scouting file from a national youth table tennis tournament. Fourteen pages, each pre-divided into boxes: height, arm span, reaction speed, direct-point service rate, pressure index at deciding points. Of those fourteen pages, only two lines are filled in: the athlete's name and the result of the final. The rest is blank, and no one on the coaching staff finds that unusual.

That was the moment I understood what years of following youth squads had taught me in the most uncomfortable way: most of what we know about young talent exists outside the data. It lives in the memory of a few middle-aged men, in notebooks gone brown, and in phone calls nobody records. I do not write about the point that ends a rally. I write about the day he carried the whole world on his shoulders after a missed serve.

The evaluation I received recently ran to nine sections, complete with charts, scoring scales, a risk framework and a probability matrix. It sounded highly professional. By the final page, every box said the same thing: insufficient information to assess. No title, no source, no core viewpoint, no named subject. That document was not wrong. It was simply honest in a cruel way.

It was built to analyse a match, an athlete, a tournament, and it failed because there was nothing to analyse. But that failure does not belong to the person who wrote the report. It belongs to an information-gathering system that has left those cells empty for years. A perfect analytical framework laid over an empty layer of data produces only the illusion of understanding.

I once sat in a meeting room at a youth training centre in Guangzhou, where the head coach required every athlete under fifteen to be re-measured on eighteen indicators each quarter. There, a child could be moved down a group simply because lateral movement speed had slowed by 0.07 seconds. At plenty of academies at home, the only thing recorded is the final ranking.

Those two approaches do not merely produce two different sets of files. They produce two kinds of athlete: one learns to trust the process, the other learns to trust the result.

The data gap has very concrete technical consequences. Without indicators, judgement retreats to feeling, and feeling in youth table tennis tends to be dominated by three things: the result of the most recent match, physical appearance, and the relationship with whoever is holding the pen. None of those appear in a scouting report. All of them decide who gets called up.

I tracked one athlete born in 2026 at a regional youth event. Over four group matches he won three, losing once to the second seed. The indicators I recorded myself showed his direct-point service rate rising from 18% to 27% after he changed the placement on his reverse-spin serve. Nobody on the organising committee wrote that down. He was cut from the training squad for being "inconsistent" — a verdict built on exactly one defeat.

This is the mechanism I call verdict by single sample. One defeat becomes evidence of character. One win becomes evidence of potential. Meanwhile the things that actually predict the future — quarterly improvement curves, the ability to correct technique after feedback, recovery speed between matches — are never measured, and therefore do not exist. A talent that is not measured will not be protected, and a talent that is not protected will be judged by the worst match of his life.

The long-term consequence lands on late developers. In table tennis, physical development and technical development do not run at the same speed. A fifteen-year-old five centimetres shorter than his peers loses the long rallies and is filed away as physically weak. Two years later, twelve centimetres taller and having learned to hold the ball in the middle of the table, nobody is following him anymore. At sixteen, people see a star. At twenty-three, they finally see a person.

After many seasons I set myself one rule when working at youth events: every athlete who catches my eye must get at least three indicators, three technical notes and one line about training context. That notebook has travelled with me for years, and it has repeatedly pointed to athletes no results table ever mentioned. Le Hoang Nam was one such case: seventeen years old, no national medal, but an unusually high success rate on backhand blocks against left-handed opponents. His scouting file at the time still contained a single line.

There is a fair counter-argument: measuring more is not the same as understanding more. I have seen thirty-page files lead to the wrong conclusion, because people measured everything except the one thing that mattered — how an athlete responds when trailing in the fifth set. Conversely, an old coach can watch a child hit for five minutes and know more than the entire spreadsheet.

That is the blind spot on both sides. The data camp forgets that data only answers the questions someone already knew to ask. The eye camp forgets that memory is eroded by the most recent match. The answer is not to pick a side, but to force both sides to write things down and cross-check each other. That demands something deeply unglamorous: time, and the discipline of whoever holds the pen.

I think of Mr Viktor Petrov, a former youth scout at Lokomotiv Moscow, who walked me through a Russian city when I got lost during a World Cup. He told me he never judges a young athlete on a single match. When the whole world turns its back, the academies still keep the lights on in the dark.

That nine-part evaluation full of empty cells is not a personal failure. It is a mirror. Every empty cell is a question nobody bothered to ask, an athlete nobody bothered to measure, a season that passed leaving nothing behind but a ranking. The life of a young talent is a run of forgotten days, punctuated by a few minutes that are remembered.

The question I carry out of every tournament is simple, and I have never fully answered it: inside those empty cells, how many athletes were left behind not because they were not good enough, but because nobody was willing to keep notes long enough to see them?
