On a March afternoon at the Hai Phong table tennis arena, a youth-team coach opened the scouting file of his U15 pupil in front of me. The first page carried a name, a date of birth, a height. The page after it was blank. Not a single figure on point-win rate, not a line of note on the wrist rotation, not a trace that anyone had actually sat down to watch the boy play. The fourteen-year-old sat a few rows away, waiting to be assessed, while the paper bearing his name said nothing at all. I once assumed this was an isolated incident. After eleven years observing academies, I know it is far more common than outsiders imagine.
In youth table tennis development, every decision passes through a chain of handovers. An observer sits by the table and records each rally: the topspin serve, the forehand loop, the silence between games. An assistant compiles those notes into a file. The head coach reads the file to decide who moves up a tier and who waits another season. Every link can snap, and when it does, nobody sees it, because the loss is not a match dropped in front of you but an opportunity that is never given.
Vietnamese table tennis has a memorable milestone: SEA Games 31, held in 2026, with the table tennis events staged in Hai Phong. The arena welcomed players from across the region, and the event brought the sport into the public eye of the port city. After the Games, enrolment in grassroots table tennis classes rose noticeably. A new wave formed, and with it new pressure on the youth scouting system.
What is striking is that this system still runs on very old methods: observation by eye, notes by hand, trust by word of mouth. I do not oppose the traditional approach, because I grew up inside it. What troubles me is the gap between the links, where data falls away and vanishes without leaving an echo.
When a scouting file comes back empty, the usual response is silence. No one wants to admit they forgot to take notes, sent the wrong file, or read the wrong column. So the blank page is placed at the bottom of the pile, and the boy keeps waiting. I call this phenomenon the handover gap — the moment information leaves one person's hands but has not yet reached another's.
For years I have tracked scouting sessions across different age groups. At U11 and U13 the problem is less severe, because the main goal is to spark enthusiasm and build a movement base. By U15 and U17, when selection begins to be tied to training-camp slots, to nutrition programmes, to chances to compete regionally, every data gap carries real consequences. A player judged low because the file lacked figures can lose a year of development — a stretch during which, at puberty, body and mind change faster than anyone can recover.
I have sat long enough beside a table to understand that this sport's data does not live in the scoreline. A young player can lose 0-3 yet possess something far more valuable: the ability to read an opponent's spin, calm under a deficit, the habit of adjusting footwork after a missed shot. None of that shows on the scoreboard, and none of it shows in an empty report.
Between a report that states plainly 'insufficient information to conclude' and one that says 'the player performed well' without evidence, the distance is greater than we think. The first is honest and can be used to plan further observation. The second creates the illusion that the process is running smoothly.
As an intern, I once wrote a long report on a small-framed player, emphasising the number of off-ball movements he made to open space for teammates rather than counting goals. The coaching staff initially ignored it. I persisted and sent it again, with specific figures. This time they took notice of the boy. The lesson I drew was not that the report was accepted, but this: had I written 'the boy played well' without figures, the report would have stayed in the drawer forever. Evidence is what turns an opinion into an actionable file.
In youth table tennis, the most dangerous thing is a file that looks complete but is in fact empty.
Pretending to have data happens in many ways. A coach writes 'forehand loop technique is decent' without saying decent compared with whom, at which event, under what pressure. An assistant copies another person's remarks without ever having watched. A file is duplicated from last season and renamed. No one means to do wrong. But the pressure to have an answer, to fill the blank before the deadline, pushes people to write something that sounds professional.
If I had to give a minimum list for a youth table tennis observation, I would start with serve variety. How many different serves does a U15 player have, and how many direct points or weak returns does each produce. Next is the third-ball attack rate — a measure of whether the boy takes the initiative after serving. Then the length of the rallies he wins, because this figure reveals his style: players who win with short rallies tend to rely on speed, players who win with long rallies on stamina and patience.
No less important are the indicators a machine cannot measure. The time the boy takes to recover his stance after a missed shot. The way he looks at his opponent between points. Whether he adjusts tactics on his own after falling behind, and in which direction. I once saw a young player turn a match around simply by changing the rhythm of his serve, and if the observer did not record that moment, the file would be left with a single line: 'won 3-2'.
Such note-taking costs time. It demands that the observer sit long enough, patiently enough, and accept that most of what he records will not be used right away. The deepest layer of soil usually tells the truest story, but few are willing to go down there with me.
There is another phenomenon I have observed across many age groups, and it is often overlooked in scouting discussions. It is that players born early in the calendar year tend to be selected more often than those born late in the year, simply because in adolescence a few months' difference creates a physical gap. Someone born in January is taller and sturdier than someone born in December in the same cohort. If the observer does not record the date of birth beside the physical metrics, he will unwittingly turn a temporary advantage into a conclusion about talent. And the late-born players, whatever their potential, are pushed back simply because of a fact that was not written down.
When I review the incidents from my working life, I realise they rarely happen at the observation stage. An observer, however tired, usually still manages to write something down. The failures happen at the handover: a file not named correctly, a verbal exchange never recorded, a meeting postponed and never rescheduled. The data exists, but it does not reach where it needs to go.
I once witnessed an incident I will never forget. A young player was highly rated in training sessions, but his official file lacked the physical and defensive sections. When the final decision came, the coaching staff chose another option, and the boy was left behind. Half a year later he shone at another tournament, with results far beyond the one who was chosen. No one mentioned the old story again. But I understood that the cause lay not in the boy's ability, but in a file missing a few pages.
I tell this story not to blame anyone. I tell it to show that our system often judges people by the quality of the file about them, rather than by the people themselves. When a file is empty, no one sees a player who was overlooked. They see only a blank space, and a blank space is easy to pass over.
At a deeper level, I believe the root problem lies in how large academies hoard talent. A centre may take in dozens of young players each intake, but only a small share of them truly have a path to the first team. The rest are kept as a reserve pool, training without a clear development plan. At that point the scouting file becomes an administrative procedure to legitimise keeping people, rather than a tool to develop them.
Alongside that is the question of competition density. At youth level, the calendar grows ever denser, and the body of a fifteen-year-old is not designed for two matches a week across an entire season. That density is the leading cause of injury, and no medical team can compensate for it. When a young player is injured, the file about him usually notes only 'out of competition', not the cause, not the number of overload days beforehand. The data on overload vanishes, and the next time, the mistake repeats with another child.
Most discussions of youth table tennis revolve around two questions: how to find talent, and how to secure more funding. Both matter. But there is a forgotten question, and it is the root one: are we preserving what we have already observed?
An academy can spend heavily on searching for talent, then let precious notes rot in a drawer. A centre can run dozens of scouting sessions, then have no one compile them to see the patterns. The effort is considerable, but the result evaporates at the very moment of handover.
I am not looking for the star. I am looking for the way people light that star. And that way, most of the time, lies in the least glamorous links: a notebook with numbered pages, a file named to the correct convention, a meeting with full minutes. No one writes an article praising such things. But they are what keep the data alive through the season.
From this angle, an old notebook is worth more than a grand scouting session. Dust covering a memory is not there to bury it, but for us to dig it up at the right moment. The pity is that in many cases, people dig too late, when the player has passed the best years of development.
Some will say youth table tennis needs better coaches, better arenas, more international competition slots. I do not deny it. But I believe the cheapest and most durable step forward lies in our stopping writing empty reports. A blank field honestly marked will save a player. An evidence-free compliment will bury a talent before anyone notices.
A youth academy does not manufacture players. It keeps the unfinished drafts of a generation. The observer's task is to make sure no page of those drafts is torn out simply because someone forgot to take notes.
