Patricia was ready for release but Pohl tested an oddly lower EAS score than what I was getting in testing.
I've been getting 475,000 locally, but he only got 340,000 EAS. I've tried a variety of different engines and time controls and can't replicate his results, I'm wondering if it might be the opening book now.

EAS cost elo :D

Or the other way around, increasing elo will lower EAS.

Exactly. Example: Each won (non-sac) game in the endgame (which old Patricia 3.1 could not win) lowers the percents of the won sac-games, because it is a win without a sac. This lowers EAS-score, of course, because all scoring is done with these percent-values.

Patricia 4 is out: https://github.com/Adam-Kulju/Patricia/releases/tag/4

I'm going to spend the next couple months trying to get Patricia to sacrifice more in games played from unbalanced books.
