You beat me to it, Brad. That's pretty much it, Graham. The one in five is *very* subject to random noise, whether it's one guess from five choices or five guesses from twenty five. It's the repetition that reduces the noise. However, with longer odds, like one in 50 (you made the brag), the random noise causes fewer false positives from the start. OTOH, to regularly get a hit on 1:50 odds would take some sort of paranormal ability, and we all (including you) know you don't have that! After all, you've repeatedly demonstrated that you don't believe you have it.
