Bah, Goob is right, no need for maths to find out:
if it was 0 and it is still 0, there's no drop. If it was 1 and it was still 1, there would be no drop. Same deal

On such matters where no negative is possible, you can't drop any further once you've reached the floor

And about the zombies and isolated case from Carl... Mmh... Principle of precedency (sp? ). If the guy is charged for the case and found guilty, wait, you zombie writer pawns

( haven't actualy read the article, I'm on uni connection wich speed is... zombi'ish

)
Oh, and Thief3 zombies would win since they can run
