Well round 1 there was around 6 zombies then I went on 10's,
R-10 33 zombies
R-20 60 zombies
R-30 105 zombies,
I'm no mathematician but im saying they average around an extra 25 - 50 per 10 rounds btw I died round 40 so I didn't get that number.

On round 99 on Black Ops: Zombies the two player or more will stop there and there will be no more rounds just an endless amount of zombies but in single player it continues. This link is of Syndicate (#1 Zombie player in the world) getting to round 105 of Kino der Toten

If you turn a trap on and stay in it, the rounds speeds up and goes by in a few seconds.
