How it works

Each of the ten events is scored with the real World Athletics (IAAF) combined-events points formula, which turns a raw mark into points on a fixed, non-linear scale:

Track (time, lower is better):
  P = floor( A × (B − T)^C )
Field (distance/height, higher is better):
  P = floor( A × (M − B)^C )

A, B and C are official per-event constants (e.g. 100 m: A=25.4347, B=18, C=1.81; Long Jump: A=0.14354, B=220 cm, C=1.4). The exponent C > 1 means marks near the elite end are worth disproportionately more — a small time drop near world-class pace is worth far more than the same drop from a mediocre mark.

This simulator does not hand-place ten results — it derives each raw mark from the athlete's four attributes (Speed, Power, Endurance, Technique), weighted differently per event (a 100 m final leans on Speed and Power; the 1500 m leans almost entirely on Endurance; Pole Vault leans on Technique and Power), plus a small per-event "form" variance you can reroll. The ten event scores sum into the total, exactly like a real decathlon scoreboard — the world record is 9126 points (Kevin Mayer, 2018); 8000+ is elite senior level.

Sliders — set the athlete's underlying attributes; every event's projected points updates live.
Run All 10 Events — animates through the events in official order (Day 1: 100 m, Long Jump, Shot Put, High Jump, 400 m — Day 2: 110 m Hurdles, Discus, Pole Vault, Javelin, 1500 m), committing each mark and its 3D scoring column in turn.
Reroll Form — draws a new random seed for the per-event variance without changing the attribute sliders, showing how the same athlete's score still fluctuates day to day.
