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.

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.
