Is spectators territory estimation supposed to be this bad?

They? Who?
You can count the score by yourself, you cannot use help to count.

Thanks, I updated katago and this seems to have fixed the problem. With my slow computer, it works best with a 15 network. At low playouts, the territory ownership estimate is sometimes correct, sometimes not.

3 playouts:

4 playouts:

11 playouts:

Generally it’s correct with 100 playouts or more:

I wouldn’t say that: it seems to me that in each screenshot it’s immediately recognizable that the board control is quite even for both players and the top left corner is unsettled.
I think it’s quite good even with few playouts.

Way different from the OP.
