"Scorers must allow for differences in the body shape and structure of each soldier. The scorer uses each soldier’s starting position as a guide throughout the event to evaluate each repetition. The scorer should talk to the soldier before the event begins and have him do a few repetitions as a warm-up and reference to ensure he is doing the exercise correctly." Furthermore, "your chest may touch the ground during the push-up as long as the contact does not provide an advantage. You cannot bounce off the ground."
That's verbatim from the FM/TC. Might try checking there next time. Also, I think this question is in the wrong forum. Might try reading what the forums are about next time too. Hope this helps.
