One second is a believable time for the drill you mention. However, your stated times of 0.075 to 0.080 sec seem off by a factor of 10. Are you sure you didn't mean to type 0.75 to 0.80 seconds? Those numbers would be attainable with practice, and would bring the various BS meters off the pegs.
Think about this as another way to gauge these times...a typical timer beep lasts 0.25 seconds. With the 0.075 sec times, you're saying your friend can hear the start of the beep, turn, draw, and put a round on target before the beep ends. Is that really what you mean?
