An Empty Data Sheet and Four Hours of Note-Taking: The Craft of a Table Tennis Analyst

Three in the morning. I open the analysis file for a WTT quarter-final, set it beside a cup of tea gone cold long ago, and settle in for four hours of note-taking as usual. The familiar table appears on screen: a score column, a server column, a rally-duration column, a footwork-position column. All empty. Not a number, not a name, not a timestamp. A data file that arrived without carrying any data.

What makes me stop is not the emptiness. It is the reflex. After more than thirty years in this craft, I know exactly what dangerous reflex shows up at the thirtieth second: the mind begins to fill the blanks on its own. A familiar name. A score I believe I watched. A judgement about someone's playing style that sounds entirely reasonable. All of it smooth, all of it convincing, and all of it unfounded.

At fifty-two, I no longer argue with a reader over a single game. I watch the whole season.

This story is not about stroke technique. It is about verification. An empty data sheet is not bad news about a player, and it is not good news either. It is a blocked pipe. If the writer cannot tell those two things apart, he turns a technical fault into a sports narrative — and that is the moment analysis loses the only thing that makes it worth reading.

Context: a sport running on numbers few people check

Table tennis in the WTT era runs on a 52-week rolling points system. Every week, old points drop off, new points come in, and the world ranking shifts. For fans, it is an entertaining game: today this player rises to number three, next week he falls to number five. For those who work in the field, it is a trap. Ranking is the output of an administrative equation, not of form. A player can hold his position for months simply because the old points of those around him expire faster than his own. Looking at the number, he is stable. Looking at the footage, he is half a beat slower.

That is why I never open an article with a ranking. I open with a small detail: the tilt of the wrist on a serve, a footwork step half a beat off when the opponent changes spin direction, the trajectory of the ball after it touches the table. None of that sits on a ranking list. But all of it is fact that can be verified.

I was wrong in 2026, when I trusted the name and not the structure.

My error that year was not underestimating a team. It was overestimating a name. I looked at reputation and history, then concluded. I ignored the structure underneath — how people organise space, how they choose positions, how they accept conceding one part of the pitch to keep the rest. France won the World Cup and I was wrong. Since then, I do not write a sentence without data behind it.

That lesson applies even more harshly to table tennis. Table tennis is a sport of gaps and spin. Whoever reads the spin before the ball leaves the opponent's racket wins. Reputation helps nothing in that instant. Only data about habits, about probabilities, about how a player reacts after being pushed into the backhand corner twice in a row, helps.

Seven minutes, seven years, and a process

In 2026, aged forty-three, I was still writing long-form analysis for a print paper and viewing the emerging sports media as noise. An editor of twenty-eight asked me to make a tactical video about a derby. I refused outright: three minutes cannot explain a match. But when a male colleague failed with a sloppy video that drew a few hundred views, I decided to do it my way.

I spent four days building a motion graphic, coding every pass, every position, every change of direction. The video ran seven minutes, carried not one wasted word, and drew over two million views. The young editor called me the diagram sorceress. What I did not tell anyone then was that those seven minutes cost me seven years of accumulation. Every frame had already passed through my eyes at least ten times in earlier matches.

Seven minutes of video, seven years of re-watching. Each time I see a different match.

I do not watch a match to discover something new. I watch a match to check whether what I saw in other matches still holds here. That is the difference between a viewer and an analyst. The viewer asks: who won. The analyst asks: why was this point scored this way, and can it be repeated.

In table tennis, this check is especially effective. A player serves reverse spin sixty percent of the time in the first game, then drops to forty percent in the third — that is not random, it is a sign of lost footwork or lost confidence. A player plays the cross-court forehand loop seventy percent of the time when leading, but only forty-five percent when trailing — that is a sign of withdrawal, or conversely, of willingness to take risk. These numbers must be counted by hand. No system supplies them reliably.

218 matches without spectators

In 2026, when the pandemic halted the calendar and then brought it back in silence, I gathered data from 218 matches played without crowds. I sat alone in that room for weeks. No cheering, no jeering, no pressure from the stands, no victory joy inflated by a crowd.

218 matches without spectators. No one to blame, no one to celebrate for. Only tactics remained.

Results: average goals in European football fell from 2.7 to 2.1; the rate of away teams avoiding defeat rose by 12 percent. Without crowd pressure, underdogs dared to defend more, to hold a lower block, to accept conceding territory. I wrote a fifteen-page report. A Championship club asked for a copy. A male colleague once joked that women worry about the stands. I answered with data about home-team psychology.

But the biggest lesson of those 218 matches was not about crowds. It was that removing one variable can change how a whole match is read. When all the noise disappears, I see decisions I never noticed before, because atmosphere had covered them.

The same happens in table tennis. Remove the applause after a fine rally and I begin to see that the rally itself was prepared two serves earlier. Remove the sigh after a miss and I begin to see that the miss was the consequence of a single wrong step at the left corner of the table.

Since then, every analysis I write carries an environmental variable: crowd, weather, schedule density, time-zone travel. I write more about the moment a player makes a decision under pressure, not only about the formation diagram. In table tennis, a player who flies from Europe to Asia within forty-eight hours and then steps to the table — that is a technical variable, not an excuse.

The ladder of verification

Over the years I built myself a ladder of verification. Any piece of information that wants into an article must climb every rung.

The first rung is source. Where did this come from, and what does the person passing it on gain from passing it on. Without an answer to the second question, the information is just a handsome rumour.

The second rung is date. Every number must carry a date. A percentage without a date is a dead number, because it cannot tell me whether it still holds. In table tennis this matters especially: a player changes rubber, changes sponge hardness, changes blade construction, and all prior statistics become meaningless within weeks.

The third rung is the unit of measure. A statistic must measure what it claims to measure. Serve-win percentage does not measure serve quality if the receivers are weak. To measure serve quality, you must measure the win rate when serving against the same opponent, in the same phase of the match, at the same score.

The fourth rung is repeatability. If a phenomenon appears once, it is an event. If it appears ten times, it is a trend. If it appears a hundred times, it is a principle. I only write about principles, and only once I have counted enough instances myself.

The final rung is limits. Every analysis must state clearly what it does not know. I end every article with a blind-spot section, where I plainly list what my data cannot cover.

This ladder does not make me write faster. It makes me write less, but more accurately.

The counter-intuitive angle: when caution becomes an escape

There is a trap on the opposite side, and I must speak about it because I fell into it.

After becoming obsessed with verification, I started to become over-cautious. I refused to write when the data was incomplete. I postponed conclusions. I turned modesty into a pretext for never making a judgement at all. An article full of sentences like we cannot yet conclude sounds very responsible, but in substance it evades responsibility.

The difference is this: modesty belongs at the point of admitting the limits of the data, not at the point of refusing to conclude once the data is sufficient. If I have counted, checked, and re-watched seven times, I have an obligation to say what I believe. A silent analyst is a useless analyst.

The second trap is more dangerous: turning a pipeline failure into a sporting signal. An empty data file says nothing about the player inside it. It says only that the collection stage broke. But a hasty writer can read it as a sign: ah, this player has problems, so nobody is tracking him. That is a leap of logic I have seen hundreds of times in this trade, and every time it produces a wholly distorted article.

In table tennis this form of distortion appears frequently around events the media ignores. A young player missing from a small event does not mean he is injured or out of form. He may be in a technical-transition phase, he may be building fitness for next season, he may simply not have been entered for internal points reasons. Three causes, three entirely different stories, and none of them can be inferred from an empty spreadsheet.

I was wrong in 2026, when I trusted the name and not the structure. And I nearly erred again in 2026, when I trusted the silence and not the process.

Morocco, Saiss, and the lesson of reading what is absent

There is one match that taught me how to look at a gap properly.

In 2026, I followed a team that reached a major semi-final conceding only two goals across the tournament, while averaging just 28 percent possession. Before the knockout round, their opponent had completed over a thousand passes in a single match. I had predicted the underdog would collapse, unable to withstand such ball pressure.

I was wrong. That team held firm on a double four-man structure, with a forward dropping deep to become part of the midfield block. I noted a thirty-year-old centre-back who made 47 important defensive actions, and what stood out was that he almost never dived in. He chose positions to block shooting angles, to force the opponent into a harder decision.

I realised that high pressing is not the whole of modern football. I shifted my focus from writing about pressing to writing about counter-pressing and the art of organising the block without the ball. I used the term moving block.

The lesson maps cleanly onto table tennis. A defender away from the table is not a weaker player. He is one who has accepted conceding the initiative in exchange for the ability to read the ball's direction. What deserves analysis is not that he defends, but where he chooses to defend, at which moment, and which of three possible directions he chooses to block.

What remains after all of it

I return to the empty data file at the start of this piece. I write nothing from it. I close it, note the date, and move to another match — one where data exists, where I can count, check, and re-watch seven times.

Over seven years I have learned that this craft is not measured by the number of articles. It is measured by the number of times I dare to say I do not know. An empty data sheet is not a story. But how an analyst responds to it is a story — about honesty, about discipline, and about accepting that the limits of data are also part of the truth.

When the next player steps up to the table, my question will not be whether he wins. My question will be: have I watched enough to say anything about him at all?
