Hi Ferdinand,
if I set Komodo to 0.30 I can delete more as 25% from the 26.619 positions I have.
Note:
The positions I have are "only" three moves after ECO Code was formed and min. 4-6 moves. Often the lines ... 6 moves length only have higher evals but are absolutely balanced.
The topic is really not easy.
If I reject now with 0.30 I have to different ECO codes no lines.
So 0.50 and -0.30 is Standard for Komodo and Stockfish. On this Standard we have to find out the settings for the others. Means if Komodo and Stockfish have 0.50 ... Houdini must have 0.60 or 0.65 but very often the eval is much higher. Or from Fizbo 0.7 or 0.75 or to many of really good positions are to reject.
Again ... this Topic is really not easy.
Example:
You can see it in the *.epd from Stockfish with analysed positions.
with 0.40 and -0.25 ... around 18.500 / 87417 I have to reject.
with 0.50 and -0.30 ... 9.441 ...
And with 0.30 ... to many!
I think 0.50 and -0.30 is absolutely OK as Standard!
