Frankly.... not sure what this is all about....For example a few other options, just for reference:
Mr. White standards: from 7 yards 2 rounds to body, 1 to head - 1.7 Sec vs 3 sec(!!!) in this drill even though the head shot is way bigger.
Also from 7 yards 2 rounds to body, reload, 2 rounds to body should be maximum 3 sec, comfortably, not 5.5 sec as in this drill. A good GM/M could do in a little over 2 sec. Some of them are members of this forum, BTW
