To put it more colloquially -- You MUST be the first one into the pot to have the best expected returns on your short-stack push.

Therefore hands 1 and 3 were bad pushes. The rest are fine.

edit -- First In Vigorish trumps even your cards. I would rather push 800 with a 72o with three folds in front of me than push that same amount into a 3xBB raiser in front when I'm holding ATo

I'm usually (key word, "usually") pretty good about that. My biggest two problems at this point seem to be waiting too late to start open-pushing (I usually wait until 4-5 BB to do this), and getting impatient in situations where, even though I am average in terms of chip stacks, blinds are going up very high with several players still left (my KJ suited hand being a good example of that).
