Ah, 2 + 1 sec hits in 1.5 seconds is 3.5 seconds total time. 2 zero hits in 1.7 seconds or 1.9 seconds (+0.1 or 0.2 secs per hit) would seem to be the better choice. Granted, that time is going to change depending upon range and target presentation.

I've had some non zero zone hits I'd have taken in a heartbeat in the real world. The IDPA tagets leave something to be desired, but as noted above , it's a game. With some stupid rules.

Tactical Police Competition scoring is 0, + 2 seconds, +4 seconds.
