In Response To: Handicap Backgammon. One start with cube. (mochy)

here are the formula

dElo = dPR*33

ppg = dElo/50 * 0.100 so ppr= dPR*33/50 * 0.100 = dPR * 0.066

These formula were empirically determined based on my own games , about 100,000 match played by Xg on GammonSite and self play by the bot.

in your case 3 PR advantage will translate to 0.198 ppg.

XG will allow to do a rollout for the initial position even with the cube on one side. Set the checker position where a resulting move revert the initial position. When you start the Ro a new checkbox will show "Roll as initial position" here is a quick RO with the cube on one side.

the RO show you are giving up 0.190 equity per game. leaving you with a large profit of 0.008 ppg
