Obv somethings working for you if your BB/100 is 24. If it starts to decline though as your sample size increases I would decrease the VPIP and PFR as they are a bit high for 2NL however I think that could also be dependent on how many tables you are playing. If you're playing like one or two and can focus on your opponents better then im sure its fine. But if you increase tables then definitely tighten your range up.
-I think the 70% c-bet is also right around where you want it to be.
-Won at showdown should not be any lower than 50% so I would keep an eye on that as well.
Thats all that I can really offer as Im starting to do some analysis on my stats as well. Check TheLangoliers video on Stars where he does a data review on someone that might be more helpful.
Anyone have any tips as to how to tight the VPIP and PFR so that they are closer together? I've read that they should be almost identical..
