To add to this, don't look at what the best shooter you know did and think you should try to do it the exact same way, especially if that would significantly change your plan. His/her plan may not be something you're capable of executing well; it's important to be aware of what your capabilities under timer-induced stress are. Just because the M-class shooter on your squad saved time by taking those two partial targets from 25 yards doesn't mean you should if there's an opportunity to take them from somewhere else that's closer/easier. (I say this from painful experience of having burned myself that way before. Mikes do worse things to your score than a few extra seconds ever will.)
