What formula does this calculator use?

It uses the published IAAF/World Athletics scoring-table formulas: points = a x (b - time)^c for running events (100m, 400m, 110m hurdles, 1500m), and points = a x (mark - b)^c for jumps and throws (long jump, shot put, high jump, discus, pole vault, javelin). Each event has its own fixed a, b, and c coefficients.

Is this the exact official scoring system used at IAAF/World Athletics meets?

It applies the same widely published a/b/c coefficients that the official scoring tables are built on, not a licensed copy of the official scoring software. World Athletics has revised scoring tables in the past, so totals here are a close estimate, not a certified competition score.

What units should I enter?

Running events (100m, 400m, 110m hurdles) go in seconds, like 11.25. The 1500m accepts minutes:seconds, like 4:30.00, or plain seconds. Jumps and throws (long jump, high jump, pole vault, shot put, discus, javelin) go in meters, like 7.20 or 14.50.

Do I have to fill in all 10 events?

No. Any event left blank is skipped and shown as not scored; the day and combined totals only add up the events you have entered, and a note shows how many of the 10 are counted.

Why did an event show 0 points?

Each formula has a threshold mark (the "b" coefficient) below which the formula would produce a negative or undefined value. A result at or worse than that threshold scores 0 for that event rather than a negative number.

Yes. Each event score is rounded down to the nearest whole point, matching how official scoring tables display points, before the events are summed into day and combined totals.
