Regressions are not run often ... it would be more pertinent to ask a) whether gnugo picks better moves with a higher node limit, and b) whether the cost time-wise is acceptable for ordinary usage.With 1000 nodes I measure a regression slowdown by 9% and with 1500 a slowdown by 17%. /Gunnar
If the moves are not better, that would be a topic for investigation; it suggests a brittle algorithm which has been tweaked to work at certain settings, but not under deeper study.
