Probably the biggest mistake u could do is aim for a "good" number.
There are many ways to play winning poker and aiming for some magic number is not one of them.
If u want to plug some leaks check the postional tab(or post a screen shot) and make sure your VP$P an PFR are low in EP and rising until u reach the btn.
You be much better of going over your current stats and seeing if there good then decited your gonna play 16/12 and 3bet 4% because some one on a forum told u that was the key to winning poker.
3Bet PF If seen winning players have from 0 to 20%
Total AFq Winning player could have 20-80.
Fold to F CBet You could probably be winning even if had a ridic high FCBET but some thing around 40-55 seems a nice number
W$SD This is probably one of the few stats where u can say 55 to 65 is good since then your not geting bluffed to much but still not going with rags to showdown.
If u want some stats evaluated just post a screenie of your postional tab and some other stats, it should give u feedback that is million times better then just "17/12 is the way to winning poker!"
^^^This is great advice. I don't recall you mentioning if you had HEM or PT3? With HEM there is a program called Leak Buster and you can display certain stats with it that shows your pos #'s and such. While you can't be too concerned about a "good" number it doesn't hurt to watch your #'s and aim for some goals while improving your game.
Posting screen shots of your #'s is a great idea. Like mentioned above, positional numbers should be higher in lp than ep. This is a mistake I've made in the past and am working on fixing.
Get a feel for where the recommended stats should be and then get a feel on how to get them there. For instance I had a very low cbet% and high fold to sb/bb steal which are opposite of what they should be at. So I worked on those and got a feel for when it was a good spot during my play to change them. I'm still working on it, it is getting better.
I should have mentioned before that my style is pretty aggressive post flop, I like to take pots down and not allow chases to the river so while I am losing out on some ev with this style, I am also taking down a lot of smaller/medium sized pots on a pretty consistent basis without a showdown. That is why my showdown #'s are high, I don't allow my opps to get there too often. This may be a leak but it's a newer style I'm trying and having some success with. I went through a period of bad beats and losing streaks and started practicing increasing my post flop aggression numbers and it's working nicely for me. I'm
bluffing a lot more than I ever use to as well with success. (This is relative to the fact that I use to be too chicken to
bluff, wasn't comfortable with it and I have significantly increased my cbets and firing off that 3rd bullet in spots I would never dream of doing before.)
So yes, while monitoring your numbers is good, do not work towards a specific number, rather a range. If you are successful with your numbers being in a certain range, although it may contradict what is recommended, then stay the course because it is working for you. Work on the ranges you know you are having problems with.
