625 and stevelyn, y'all don't understand what a double tap is. It isn't two shots and a pause. If you want to pause, that is your call, but a pause is NOT part of a double tap sequence.
A double tap is one sight picture and two rapid trigger pulls. Assuming your target isn't moving quickly, one sight picture and two fast shots should land both on target, if you have practiced this. You save the small amount of time required to let the sights settle between shots. This is something like 1/4 or 1/2 of a second of additional time. However, by the time you get off your double tap, the sequence is not continued as you aren't aiming the latter shot(s) and your subject may have changed position, gone down, or whatever. What a lot of folks consider being the assessment time after the double tap should be nothing more than letting the sights settle for a new proper sight picture before you start your next shot(s) if they are needed.
As STEVE M mentioned, there really should be no pause to assess. If you are thinking that hard, then you are moving too slowly. The notion of pausing to assess gives the impression of stopping your action, thinking, arriving at a decision, then acting on it. A running back going down the field will attempt to evade an defensive player trying to tackle him. The running back does not jink a couple of times and then stop to assess whether his move actually confused the defensive player or not. Nope. He continues to adjust his activities on the fly in real time.
