I started out at Level 3. L3D1 measured up to about 60 rounds. I really have no problems with pull-ups. I do HATE push-ups. L3D2 was hard on me, mainly push-ups. I barely take more than 10 sec in between rounds. I don't like to wait time during workouts -- trying to train and condition my endurance. Managed to complete day 2 in 6:40 (rest time included).
Day 3 will be interesting. 33 push-ups can be a bitch! I will let all know how fast I can complete L3D3 later.

Cheers!
