sprt @ 10+0.1 th 1 My resolution series has the intention to lower the noise in computed stats (shows some very little gain so far). Now i try to go from the opposite site and filter the noise of the update values by decreasing the stats bonus by 1. For depth 1 (the noisiest one) we get then a bonus of zero, which avoids stats updates.
