Decathlon Score Calculator
This scores a decathlon using the World Athletics combined events tables, the same ten formulas in force since the 1984 revision. Enter all ten marks for a full score with the day one and day two splits and a per-event breakdown, score a single event on its own, or work backwards from a points target to the mark that reaches it. Running events use points = a x (b - T)^c and field events points = a x (P - b)^c, with each event truncated to a whole number before the ten are added. Every result carries a self test that rescores Kevin Mayer's 9126 world record from its published marks, so a mistyped table constant shows up immediately. Wind, altitude and hand timing are not adjusted for; the tables score the mark as written.
