I tried pearson correlation in the past, but it's not a good measure. Right now my experiments with evolving the eval parameters use texel tuning on a set of 100K positions (so I can train ~6000 models per day).

In terms of the error rate, I got very close to the hand tuned model (stable version). If you want to see the fully automatic trained eval with almost 0 human intervention check [1] or [2]. The evolved version is 100 Elo weaker than the stable version of Zurichess. I need to add back the pawns cache, though.
