Mercier Scoring Tables – Although many years out of date, this calculator is still useful for comparing results across events: “Originally devised by Daniel Mercier, the Scoring Tables are the result of a statistical comparison of all performances in Athletics…they are the end-result of a linear fit to the weighted average of the 5th, 10th, 20th, 50th, and 100th World-ranked performances in each event [over the years 1995-1998]”

Somewhat newer Mercier Scoring Tables – Same as above, but more up to date (incorporates IAAF statistics from 2005, 2006, 2007 and 2008)
