"Easy" improvement to PR calculations

There are a lot of different issues here. I'll just point out the one that stands out most to me. The goal of getting a better fit to our intuitive notion of "what is a decision" seems orthogonal to the goal of having less variance from game to game. For example, my impression is that Snowie ER gives less variance from game to game than PR does. With PR, every now and then I'll make one opening blunder, get blitzed and gammoned in a long game, and wind up with a PR of 20+ for the game. I don't track Snowie ER systematically but I'd be surprised if I've gotten an ER of 20 in any game I've played in the past five years.
