I would have thought that if I were running a command file with a few
rollouts in it, I'd like to be able to see what sort of progress it
was making - an untruncated rollout of 6 moves can take a couple of
days even on a 2.4G machine with lots of memory. Personally, I'd want
to see how far it had got and be able to estimate how long it would
take to complete and what sort of results it was showing (if it's
rolled out 400 games and the STD of the results is down around .0015,
I might decide to stop it there, even if it meant editing my command
file to start with the next position, rather than run another several
hours of rolling out a position which I think is already clearly
evaluated.
