Heptathlon calculator

Every event is scored on its own with the formulas published in the World Athletics (IAAF) Scoring Tables for Combined Events, then the event scores are added. The tables printed in that book are generated from these same formulas:

Each event score is rounded down to a whole number before it is added (123.999 becomes 123). Hand-timed races up to 400m are scored as if they were 0.24 s slower (0.14 s for the 400m); there is no adjustment for the 800m, 1000m or 1500m. The calculator first records a hand time to the next tenth, as the timing rules require.

We checked this calculator against every mark covered by the book's printed tables (147,375 marks across all events, electronic and manual timing). It agrees everywhere except three marks where the printed table skips or misprints a row. There we keep the formula, which the book gives as the scoring method. It also reproduces the book's sample score sheets from the 2001 World Championships to the point.

The constants for each event as printed, plus the weakest mark worth at least 1,000 points (electronic timing for races):

Jackie Joyner-Kersee, Seoul 1988 (world record): 7,291 points. Each line below is the formula above with the mark plugged in, rounded down.

Three of the seven women's events are races: 1,000 points takes 13.85 in the 100m hurdles, 23.80 in the 200m and 2:07.63 in the 800m. The men's indoor heptathlon (60m, long jump, shot put, high jump, 60m hurdles, pole vault, 1000m) uses the men's decathlon tables for the field events plus its own indoor tables for the 60m, 60m hurdles and 1000m.

The decathlon calculator scores ten-event competitions. For a one-day indoor competition, the pentathlon calculator covers the women's and men's indoor pentathlon.
