One thing about YACE learning feature that I dislike is that it doesn't
overwrite the same position when importing it.

For instance my YACE learnpos.bin has "28169" positions. But all of them are not
unique position. If I try to import 30 positions from learnpos.yac 5 times it
will add 150 new positions, so it will add the same positions 5 times. I don't
know if it does the same thing during a game. If it learns from a position it
reached and learned before, does it overwrite it with a new score or update it
with a new score?
