How the rating system works

Credits

Many people have been contributed to the creation of the ranking system. However, special thanks are due to:

Gerben Dirksen, for having the idea, devising the original formula, writing the first program to calculate ratings, administering it for most of the first year, and providing useful advice and mathematical assistance ever since.

Graham Hazel, without whose software none of it would have been possible.

Chris Dixon, for sorting out the problem with serving that had been causing anguish for five years.

Stephen Frechette and Aashish Welling, for giving us a brand-new web-based version of the software in 2020.

Steve Altus, David Beer, Lew Stansby, Neil Trentham and Giles Woodruff, for providing advice and comments on the ranking system.
