Starting the clock after a penalty Federation

I think the game situation also effects your response. If the ball is 1st and 10 on B30 near the end of the first half and B is out of timeouts, I'd go on the ready for sure on the first time and probably the 2nd false start also. If it is 3rd and 20 from the A5, the first false start would be enough to wait until the snap.
