Playing around with Holdem Manager I found that you can fliter hands. Specifically I found the filters

Could of C-Bet
Did C-Bet

on flop, turn, river.

So I set these to find out where HM would suggest I increase my aggressiveness.

My question is has anyone used these filters to learn? What was your experience? Any other useful filters you would recommend in order to learn how to play better/more efficiently?
