In Response To: Or use XG's Elo Calculator (neilkaz)

Based on online games from GammonSite, I came up with the formula Delo=epd*16500 (eqd is equity lost per decision). PR=epd*500. so it resolve in PR*33=Delo.

The elo fomula is the usual one for online site: P=1/(1+10^(delo/2000*sqrt(N))

So there is a relation between Elo and PR if we assume there is one between Elo and epd.

The formula i gave Delo=epd*16500 works for good enough player (less than 10 PR). for a more accurate formula check http://www.bgonline.org/forums/webbbs_config.pl?frames;read=66981
