How to interpet Turn cb stat depends allot on his Flop Cbet and Opening range.

For example, say some is a extreme nit and opens only AA. His flop cbet will be 100% and his turn cbet 100% as well. This is of cource since he has a verry good hand all the time.
Of cource extreme example, but i hope you get the point.

Now when someones Flop Cbet is verry low, but his turn cbet is high, this is mostly because he has strong hands when he bets flop and get to the turn that way.

To answer your questiong turn cbet around 55-65% are average. Higher than that is allot, lower than that is verry little but ofc this is related to the cbet stat.

Open range and flop cb stat is more important. Turn CB depends on the two and takes longer to converge as well.

I have a pretty intense HUD for heads up. But I find myself paying the most attention to the blind specific stats like:

Big Blind:

Fold, Call, 3bet

Small Blind:

Button raise, limp %, limp fold, limp call, limp raise

Aggression stats:

I like to have all the AF and AFq stats including the street specific stats.

This will help you get a bigger picture on any glaring tendencies villain might have.

Cbet:

the fold to cbet and cbet flop stats are actually going to take a while to converge, so you should always take these with a grain of salt. I like to have a big Flops Scene: # in the top left so I know how many flops I've seen with villain. You can use this to give your cbet flop and turn stats more or less statistical significance. 

But to be honest, the only ones that will really converge are the open and call stats, and maybe the AFq stats after a fair amount of hands.

Most of the time, if I haven't cleared someone out in the time the other stats start to converge they are probably a decent player and should not be given any more action anyways.

I think the limping stats are not that useful Mush. 

Look more into Barreling Flop/Turn/River stats. 

F2FCB stats, etc. I think your overall stats are more adjusted for analyzing Preflop scenarios.

The main one I was talking about is the limp %, because then you can start to see how they split their SB VPIP into limp% and button raise %.

By barreling stats you are talking about a turn barrel being defined as bet flop, bet turn, and a river barrel defined as bet flop, bet turn, bet river right?

correct

Do you find the statistics in 3bet pots to be useful? So far the only one I have is CB in 3BP but I think I should add a section in my HUD just for 3BPs.

Don't quit a 'decent' player if you want to improve your game. They have more money and the fish wont show you your leaks ;D

I agree that the preflop stats are the most useful, aside from when someone comes back after a few days, then the others can be used as a guideline as well if you don't make notes.
