Vietnamese Table Tennis and the Lesson of a Blank Cell in the Data Sheet

In 2026, at a national table tennis championship, I sat in the third row and recorded every point of a men's singles quarter-final. Afterwards I opened my notebook: there were points, durations, even scribbles about the footwork rhythm of both players. But when an editor asked me exactly one question — "What percentage of points did the winner take on his own serve?" — I had nothing to answer with.

That cell was blank. An abandoned stand can still hold the echo of old applause, but an empty data sheet holds nothing at all, not even its own error.

Fifteen years in this trade taught me that most mistakes in sports journalism do not come from writing something down incorrectly. They come from nobody writing it down, and then somebody having to write anyway.

Table tennis is neglected on the data side

Table tennis is the most easily digitised of all combat sports. Every point has a server, a receiver, a rally length, a spin type, a placement. Within a single set you can measure serve-point win rate, receive-point win rate, the share of points ending within the first three shots, and even backhand usage at 9-9.

At the elite global level, the ITTF ranking system runs on a rolling 52-week mechanism; since WTT launched in 2026, every match has become an automatically recorded dataset. Live data providers sell point feeds to platforms, and part of that flow ends up in the betting market.

Vietnam sits outside that current. Nguyễn Anh Tú, Đinh Quang Linh, Trần Tuấn Quỳnh and Nguyễn Khoa Diệu Khánh remain familiar faces, but if you want to know what percentage of serve points a player won at a domestic event, almost no source can tell you. The news stops at scores, medals and gut-feel commentary.

In 2026, at the World Cup in Russia, I mispronounced the name of an African team's goalkeeper three times in the first half. That embarrassment in Russia taught me that ignorance is a starting point. I spent a month rewatching footage and built a database of more than 300 players. Since then I have not written a name or an index I had not re-checked.

But re-checking only works when there is something to check. With Vietnamese table tennis, what I usually receive is a blank.

When a cell is empty, the honest answer is to say it is empty

There is a rule I keep as a ritual: when a data field has no value, the only correct result is "insufficient information to assess". It sounds trivial, yet very few people will say that sentence.

When an empty cell is left unattended, three kinds of filling tend to appear. There is the filling with a plausible-sounding value: nobody measured serve win rate, but an article can still say "this player serves dangerously" — which is not wrong, just unverifiable, and it will live on in later articles. There is the borrowing of data from another context: a European player's indices at a world championship are used to describe a domestic player, and nobody cross-checks. And there is the transformation of scarcity into style: "the hidden variable", "the mysterious destination", "an upset that cannot yet be explained".

An empty data cell does not generate truth on its own; it generates conjecture, and conjecture always has someone willing to pay to hear it. That is why I regard the sale of live data feeds to betting companies as the darkest underside of sport's digitisation. Where official information stops, the market fills the gap with rumour, and the price paid is the credibility of an entire sport.

In 2026, when arenas closed, I wrote the series "The Lonely Run" about athletes training alone on rooftops and in living rooms. There were no tournaments, no scoreboards, but there was still information — it simply took another form: training diaries, run times, the number of repetitions of a single service motion. The absence of official data does not mean the absence of fact. It only means you have to go and record it yourself.

For table tennis, that is entirely feasible. A domestic event could record four fields per match: serve-point win rate, receive-point win rate, the share of points ending within the first three shots, and the score at the decisive points. Those four fields are already enough to tell a story that a 4-2 scoreline cannot.

The counter-intuitive point: the problem is not a lack of data

The conventional view is that Vietnamese table tennis lacks data. Based on my experience following matches and domestic tournaments, the problem lies elsewhere: we lack the habit of leaving things blank.

An editor would rather receive a wrong value than an empty cell, because an empty cell forces him to explain. A fan would rather read a confident judgment than read "insufficient basis". When content is generated automatically at high speed, any blank is filled within seconds, usually by something that sounds very persuasive.

The belief that more statistics is always more correct also deserves challenge. A wrong index is worse than an empty cell: an empty cell can be filled again by observation, whereas a wrong index gets cited, then cited again, until it becomes the shared memory of a generation of fans.

The long analytical document I recently received is a case in point. It was asked to dissect nine dimensions of an article — technique, player data, event system, competitive landscape, rules, coaching staff, risk, narrative, and industry value chain. The input was empty: no title, no source, no information points, no entity named. The honest handling was to record exactly that fact in every section, rather than fabricate players, rankings and results that do not exist. The greatest value of that document lay in its willingness to say it had nothing.

Takeaway

If Vietnamese table tennis could choose only one thing to do next season, I would want it to publish complete serve statistics for a domestic tournament. The next medal is still precious, but a results sheet with no empty cells will change how people understand this sport for far longer.

Fans may not be in the arena, but the arena is never short of them. One day someone will open our data sheet again looking for answers. Best that they find them.
