Suggested Idea for Performance Grading

Thanks for the response. If I understand correctly, your 4.5 to 6.0 zone is based on the assumption that humans won't be able to eliminate their checker-play errors entirely.

I still think that if you did actually eliminate all your checker-play errors, then the "winning zone" would be much better than 4.5. There is in principle a straightforward way of testing this to some extent. Take a large selection of your tournament games, making sure to include ones where you feel confident that your cube "errors" were actually correct in practice against whatever opponent you had. Analyze them with XG, but then go through afterwards and click on "clear analyze" for all your checkerplay errors (but not any cube decisions). This will cause XG not to count any of your checker play errors against you. I would guess that if you did this for, say, 100 matches, your PR would come out lower than 2.0.

My estimate is that checkerplay errors count for about 75% of PR. If you cut your checkerplay error rate down to zero, it will dramatically improve your PR. The occasional double-digit cube PR won't hurt you that much. Certainly bluff doubles on the order of 0.1 or even 0.2 errors aren't going to drag you into 4.5 territory if you're making no checkerplay errors.
