Well, I know a little bit about stuff like pseudo vs. "real" random number generators and their various applications, but I've never run across that particular distinction before, so I guess, yes, it would surprise me!
Is that out of computer science or math or ...?
However, the bunching I've been seeing couldn't be attributable to the occasional repeated number (you meant consecutively or, in relation to this problem, nearly consecutively, right?) unless the generator is pathological, which is what I guess I am asserting.
(Hey! In that post to Midnight, that last phrase should be "or do I have you backwards?".)
