My question was how to interpret a large positive value like 41.5%. In my view the full interpretation table is something like

-30% : blunder

-5% : mistake

0% : good move

5% : LZ admits it slightly misjudged the previous position

30% : LZ admits it severely misjudged the previous position

Do you agree with this table? If not, then how would you express the meaning of a large positive value like 41.5% in English?

Since I’m worried about a bug but you’re not, I investigated a bit more. When I analyze the example game on my computer with the same network and the same number of playouts (200), the winrate doesn’t change at all at move 42 (D13 0%). The largest positive change over the entire analysis is 8.8%, and this number drops to 6.7% with 2000 playouts.

This support my claim that seeing 41.5% in the preview and so many moves above 10% indicates that something is not right.
