The number of nodes is calculated as n mode 2^32. The numbers also suggest that your explanation is not the right explanation. We have: Depth: 24 00:38:17 3500682kN 26.axb5 axb5 27.Ra5 g6 28.Bb6 Qe8 29.Bd1 h5 30.Nf1 Nf6 31.Nd2 ² (0.67) Depth: 25 01:30:55 4282117kN The time is more than twice but the number of nodes is not. If we assume that deep junior dropped a digit then 03:17:03 1734361kN means that the number of nodes here is more than 4 times bigger when the time is only slightly more than twice bigger. It is not logical. Uri
