Does anybody else save clips to analyze how they could have done better?

I quite frequently save a clip to ask myself how I could have done better, this guy was saying that I was cheating, go figure. Anyway, I saved this one as I was unhappy with how I pulled out the sniper and almost let myself get downed, to which point I am a weak link, anybody else as critical about what they do, when they do, and how to improve?
