If anything math tells you this should be the opposite.
That you should bet less on the flop and more on the turn or that you should bet less in small pots?

I'm obviously clueless.

Another thing is that I feel like if I bet 3/4 pot on the flop in a limped pot situation I often get multiple callers and my good but vulnerable hands definitely don't want that. If I bet 3/4 pot in a raised pot situation, then it generally clears the field.
