This is one of the things that has always bothered me about Merge Factor. We state what the lower bound is, but we don't doc the upper bound. Should we even allow higher values? Of course, how does one pick the cutoff? I've seen up to about 100 be effective. But 3000 is a bit high (although, who knows what the future will hold)
