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.
