Youre assuming that an ep min raise means the guy has a big poclet pair. I dont think you will see that play very often at all (maybe in mtt or sng). An aggressive player that might try to 4 bet you with a marginal hand isnt min raising from the ep period. I think 9/10 times you are against marginal overs or another pp that you may be able to push them off of on the flop. The four bet situation you are describing just isnt going to happen very often where reraising preflop is a bad play.
