In Response To: Elo difference mapping to Snowie ER (Timothy Chow)

"So a difference of 1 Snowie ER should be a larger Elo difference than a difference of 1 XG PR, as Neil correctly calculates."

Yes, I agree with this. My mistake. A player averaging 4.0 ER plays worse than a player with 4.0 PR. So they should have a larger Elo difference from perfect play. That means if 1.0 PR is about 33 Elo, then 1.0 ER is about 36 Elo.
