Set a checkmark in the box at Use Performance Rating. On the Home page of extreme gammon, you can read in the faq: "Can I see the Snowie Rating? A: No. Our take on the Snowie Rating is that it is inherently flawed. Snowie rating is the amount of equity (normalized) lost multiply by 1000 divided by the number for roll (for both players). The main problem of it is that it does not take into account forced moves or moves that are completely unimportant. For instance in Snowie, if you play a game and reach a position where are 100% sure to lose and play the next 10 moves rather than resigning your rating will be higher! That surely does not make sense. Another case where the result is not proper is if your opponent makes a big mistake at the beginning of the game, get hit and dance for pretty much the rest of the game. His Snowie Rating will be very low because of all the moves you made and was sitting on the bar obviously making no error. But, after all, he was given one chance to show your skills but made a bad choice. In my book, he played bad every move and should be rated very poorly on that game.

We are committed to make eXtreme the standard in Backgammon and bringing back old system that we don't believe in is not something we want to do. Since Version 1.10 eXtreme Gammon has the ability to display the Performance Rating. It is the equity per decision multiplied by 500. So the number are in the range of Snowie ER, but still take into account that force move are not to be counted."

If you look in the help section of your XG installation, there are also information about Performance. Interesting, that the dorbel opinion 1900 at fibs is the new 1700 is matched by XG, if you look at performance, label and elo rating. And i think, 2000 is the new 1900. If you play 2000 at fibs, there is hope. But you are still a fish for Stick. Just my opinion.
