I love the c-bet stats. If someone has a decent PFR and c-bet every flop they are great floating targets. I float with any 2 if the flop is unlikely to have hit them. Also a lot of players fold to c-bets ~66% of the time. I know these players never call unless they hit the flop. So I just c-bet 1/2 pot instead of my usual 2/3 pot and shut down on the turn, unless I also got a piece.

Here is another thing that's good to know:

Any paired hand makes up for ~0.45% of someones range.
Any unpaired hand makes up for ~1.2% of someones range.

So if someone raises only AA, KK and AK his PFR will be around 0.45 + 0.45 + 1.2 = 2.1
