In Lizzie, why is the "move the bot would chose" not the one with the highest percent?

I know that LZ has no training based on human games.

My question was about the number of playouts. I’ve seen Mark suggesting something like 800 or 1000 playouts on LZ, while with Leela 11 I used to let it do many more: sometimes the best move is still changing after tens of thousands simulations.
