Blank Dossiers on the Table: The Data Gap Eroding Vietnam's Youth Scouting

In a small room behind the stands of Phan Dinh Phung arena, I reopened a scouting file that still smelled of fresh paper. Four days of competition, six finals, thirty-two athletes in the U17 age group. But when I turned to the technical notes, most of the boxes were empty. No spin data, no placement distribution, not even a line about psychology at the decisive points. Only the scrawled handwriting of the record-keeper, jotted hastily in the third game and then abandoned. I sat quietly for a long while. In more than twenty years holding a pen and nearly thirty years close to the table, I had never seen a dataset so blank. Notably, that tournament was far from dull. It was the counter-loop exchanges in the semifinals that brought the crowd to its feet. The problem lay in the recording stage, in how we treat data before it can settle into the memory of a generation of athletes. Every generation of athletes is a stratum; I simply sit down and listen to the echo. But that echo only sounds if someone has recorded it. When a generation leaves the court without leaving a file, every later analysis is mere guesswork. And guesswork, in scouting, is a debt whose payer is always the athlete himself. In youth table tennis, data is no luxury. A game lasts only a few minutes, yet contains hundreds of small decisions: choosing a rubber, changing rhythm, looping with spin or flat-hitting, stepping back from the table or pressing close. Four axes must be recorded clearly: technique, tactics, physicality, and psychology. Miss one, and the athlete's portrait is already distorted. Lose all four, and only a name and a score remain. In today's scouting context, it is this very void that is the alarming news, not a temporary failure of a few score sheets. For when there is no baseline data, the analyst is forced to fill the gap with inference. A technical description that sounds entirely plausible can be constructed for an athlete whose spin was never measured. A judgment about composure can be written without anyone having re-watched the decisive rally. I looked more closely at what remained of the file. There were a few handwritten lines about the tactics of the two athletes who reached the men's final. The record-keeper noted briefly that one specialized in short serves and then waiting to counter-loop, while the other preferred long pushes and attacking first. But the win-rate by serve type was left blank. Whether the first felt nerves at the decisive points went unrecorded. Yet just three days later, reports appeared declaring him 'far more composed.' People see the score; I see the silent rallies years earlier that were never counted. The root of this void does not lie in the awareness of the professionals. Record-keeping assistants at youth tournaments usually work alone, at the edge of the court, watching the ball and writing at the same time. They have no equipment, no unified form, and no one cross-checks the results after the tournament. A coach from one academy records in his own way, a scouting specialist in another, and no system reconciles the two. When comparison is needed, we discover we hold two different languages for the same event. This is especially damaging at U17 and U19, the stage where the development curve changes fastest. At this age, an athlete can improve markedly within six months. Without quarterly data points, no one can tell who is genuinely rising and who merely caught one hot match. And when two time points are merged into one, every comparison across generations becomes meaningless. A generation is examined within its own setting, not through the frame of a decade ago. Lessons from strong table tennis nations show that data has become part of coaching culture. Japan and South Korea build youth athlete files by domestic competition cycle, tied to consistency indices in international matches. When comparing with the region, we often speak of expertise, of coaching experience. But the largest gap lies in the data layer, the layer that silently decides who is promoted to the next tier and who is left behind. The three-source verification principle, which I have followed since my editorial years, can be applied immediately at the smallest scale. A judgment about serving technique needs two independent recorders. An assessment of psychology at the decisive point needs at least one replayed clip alongside a transcribed record. A physical assessment needs a specific measurement, not just a feeling. Only when these three layers align do we earn the right to put pen to conclusion. The trouble is that no one checks these blank files until they are passed up the chain for analysis. When an empty dataset reaches the person doing the evaluation, invisible pressure pushes toward filling the blanks with plausible-sounding conclusions. That is the most dangerous trap of the profession. An honestly blank file is still better than a file full of errors. If information is missing, the only correct answer is to state clearly: insufficient data to assess. Some will say Vietnamese youth table tennis is still lacking, and building a data system is a matter for the distant future. That mindset makes us bury precious artifacts from every season. A failure at a youth tournament should not be forgotten; it should be excavated as a dataset, dissected to find structural causes. But to excavate, there must first be traces to dig. The mistake of a given year is not meant to be buried, but to be revisited every time the qualifiers are mentioned. The counterintuitive angle here is this. We often believe that an observer's experience is enough, that a seasoned coach needs only a few matches to spot talent. That experience is genuinely valuable; I do not deny it. But experience cannot measure the rate of improvement, cannot compare consistency across two tournaments, and certainly cannot replace leaving evidence for the next generation. The teacher's memory is a treasure, but it is also the most easily depleted. A full notebook will outlive anyone's memory. A contract is never an endpoint; it is a piece of a long excavation. So is a single promotion. When we hand young talent up to the national team, we are handing over an entire chain of undocumented decisions. If that chain breaks, the recipient must start over, and the athlete must prove himself again before an entirely unfamiliar group. That is the silent cost of every blank file. So where should the fixing begin, and how, in a way that suits a domestic youth tournament? I believe it must start with the smallest thing: a unified record form shared across academies. In it, every athlete has four fixed boxes for technique, tactics, physicality, and psychology. Each box has a three-level scale, plus one line of notes. Simple enough that a recorder can fill it while watching the ball. From that small frame, a new data stratum can take shape. Next comes post-tournament cross-checking. Every file must be read again by a second person who marks the spots lacking evidence. Those spots are left blank, rather than filled with feeling. This is the hardest discipline, because it runs against the wish to conclude quickly. But if maintained, we gain a trustworthy dataset that can be reviewed a decade later. Finally, I still believe in the human factor over any spreadsheet. Data does not replace the coach in scouting; it only keeps the teacher's memory from fading and keeps judgment from slipping. A mature youth table tennis scene is not one where no one errs, but one where every error leaves a trace the next person can read. I folded the blank file and placed it in the drawer with the others from many seasons past. Outside, the light still shone on the blue table. A new U17 generation is entering the next round, carrying rallies no one has yet counted. My job, and that of anyone sitting at the edge of the court, is to record enough that the future need not guess. If we patiently peel back these strata, one day we will read the signature of fate that this young generation left upon the table.
