For money play 0.100 ppg is equivalent 50 elo (40 if playing Nackgammon) so dElo=ppg/0.100*50

Here, making the different versions each other is not possible: it will take far too long (months if not years) to reach statistical significance.

The benchmark is done by letting XGroller(1.04) self play (money game and Matches).

Then we analyze everthing using XGroller+. Then we Rollout (3-ply 1296 games) any differences (even insignificant). Then you sum up the equity differences (positive if XGRoller+ picked the best play, negative otherwise).

That give you the equity per decision differences betweeen the 2 modes. To get the elo from that, the formula I use is dElo = epd*16500 (the constant has been determined empiricaly)
