I reckon you could get away with a longer interval than once a second.
Does a 0-ply rollout take less than that. Two ply rollouts certainly
take a lot longer. The 2-ply rollout I have on at the moment is taking
at least 30 seconds per play.

Of course, there is a diminishing increase in effiency as the update
time increases. A 10% increase @ 1 seconds won't escalate linearly.
