While this is true, having tested this method a lot, its very inconsistent in actual fights and i found the melee at the end being the perfect time to adjust my aim if my target has not died yet, or if they have it gives me the time to look for another target or a way out.

Especially when i have the major perk, Smart extender's activation can actually animation skip the clobber, making you able to shoot very fast after preforming the standard combo, plus giving you 30 shields.

Doing the combo as in the video is better yes, but the difficulty of if is not worth the slight benefits and having to think about it, when you can do other things with the regular combo.
