Nine Empty Columns: Who Guards the Chain of Custody in Athletics Data

Last week I opened a file on my laptop that I had named Deconstruction. Nine stages, one verdict box under each, and every box carrying the same sentence: insufficient information, cannot assess. I counted eleven cells that were entirely blank — no athlete's name, no mark, no competition date, no wind reading, no entry list, not a single line on source quality.

I did not delete the report. In Kazan I learned to count frames the crowd never sees. After France beat Argentina 4-3 on 30 June 2026, I frame-counted Kylian Mbappe's sixty-metre carry and set it beside force-plate data from Karnataka sprinters in my Bengaluru lab; that video has passed 380,000 views. The empty report now sits in the same drawer — a record of what is not there.

Losing data is nothing new in South Asian domestic athletics. The national championship final walks in as a Navy-Army-BKSP procession and we keep calling it a competition. The split-time series began as a way to survive blowouts, hunting for at least one timecard inside a lopsided field; a while later it became clear the timecard itself was the problem.

Most of the storytelling around the 1980s and 1990s SAF sprint era rests on hand-held watches. The spread between hand timing and electronic timing can run five to seven per cent — a 10.50 mark may never dip under 11 seconds on an electronic clock. Compare the old days to today without that caveat and you have not built an analysis, you have built nostalgia.

The data is not missing because nobody ran. It is missing because nobody wrote it down properly. After Mahfuzur Rahman Mithu's 2026 hurdles gold, the monitoring infrastructure that was supposed to grow in this region did not.

Open the file of almost any sprinter who emerged in the years since and you find numbers sitting alone — which competition, which method, which timecard, nobody can say. Entry lists do not match start lists. A training run at a camp reaches the press, and an unofficial mark later circulates as a national best, even though it never happened at a ratified meeting, has no wind gauge reading, and never entered the ratification process.

From training to competition, the whole pipeline lacks a timestamp. Who wrote it, when, from which device, and whether it was altered afterwards — none of those answers is stored anywhere.

The telling part of that empty nine-dimension report is what it asked for. Stage one wanted performance numbers — mark, qualifying status, season ranking, wind or altitude adjustment. Stage two wanted athlete condition — age-curve position, season form, injury history, peaking schedule. Stage three wanted the three qualification routes — direct qualifying standard, world ranking points, national selection.

The remaining six stages wanted the competitive landscape, rules and anti-doping compliance, the training system, a risk matrix, narrative sustainability, and the industry ripple effects. Every one of the nine stages came back with the same result.

This is not an analytical failure, it is a measurement — a measurement of which route the input line travelled. Where a qualifying standard should sit, there is a zero; where a wind reading should sit, there is nothing. Stack the empty boxes side by side and a picture forms: around the slice of subcontinental athletics that numbers can capture, a large paper void that nobody has filled in.

The world ranking arithmetic is not actually complicated — record the bad results too, and the average still tells you something. But without a written record, tracking where an athlete stands becomes impossible. If a federation cannot know how someone's season went, on what basis does it pick a team?

That void splits into three kinds of marks. The first is the hand-timed mark, where the person holding the watch is recorded nowhere. The second is the unadjusted mark — a tailwind above 2.0 metres per second removes a sprint mark from record consideration, yet that condition is the one most often dropped from our discussions. The third is the unratified training mark, born outside a stadium, never entered on any meeting's start list.

This is where the question of data custody arrives.

At international level, ratifying a 100m record requires the federation to separately obtain the wind reading, the photo-finish image, the timing device certificate, and the doping sample chain of custody. Marcell Jacobs' 9.80 in Tokyo 2026 or Neeraj Chopra's 87.58 metres survive because a documented process sat behind each of them. The chain is a single object; tear the paper at one link and the whole number is worthless.

A timestamped record layer that cannot be altered afterwards protects a large part of that chain. Who wrote the number and when, which device it came from, whether anyone touched it later — those answers no longer rest on a coach's memory or a lost file. A blockchain-based ledger genuinely helps here, but no ledger can reach the human who was typing before the number ever entered the timing system. If the sensor sends a wrong reading, its cryptographic hash will sit there forever as a wrong reading.

The reflex answer is that putting every number on a chain restores trust. What Kazan taught pulls the other way. The official record and the video frames disagreed, and no ledger was needed to catch the gap — what was needed was one person sitting down to count frames. If the measuring point is broken, its verified copy is just a verified error on file.

The frozen contract was never about money; it was about motion. In the services-based structure of Bangladesh and India, the athlete market is set by paperwork and recruitment, not by clubs. Where someone trains, whose flag they run under, which championship calls them — that is decided by whoever holds the paper. A ledger does not free anyone here; it only records who holds the key.

In the next cycle the question will not be whether verification is possible. It will be whether anyone funds the boring layer — a calibrated wind gauge, a service contract for the photo-finish camera, and one person whose only job is to write the number down before the stadium empties.

The road of forgetting built between Mahfuzur's 2026 and today will not be paved with ledgers. It will be paved with people. Until then the reports will keep coming back with empty columns, and we will keep describing those empty columns as analysis.
