That's simple (at least I think). The scaling law converges at some point where the speed (or more thinking time) benefits little. Zen19D already reached that point and Zen19S's rank is lower than Zen19D's. Facts: Zen19D and Zen19S share the same binary (version 7.7d9) and hardware (6-pc cluster; 26 cores total). Only the time setting is different. Zen19D and Zen19S play every move in 13 and 28 second, respectively (2 second is a margin for the network delay). Human players have 9 x 15 second with Zen19D and 20 minutes + 5 x 30 second with Zen19S. Recent ranks on KGS are 5.4 dan and 4.5 dan for Zen19D and Zen19S, respectively. Additionally, since Zen19 (version 7.7) is ranked 4.4 dan with the same time setting as Zen19D, 8-core Xeon seems not fast enough to reach that point.
