For every line that you find yourself often don't knowing what to do you either need HUD or popup. Every session you play make notes while playing what data you needed but you have not had it. After session add some stats to HUD. Every week or two look at you HUD again. If you don't remember what certain stat is, then remove it from HUD completely or to popup.
Someday you'll have a better HUD.

name / hands / BB
vpip / pfr / afq / wtsd / fold bvb
positional first in / ft3b
cb flop/turn / ftcb oop/ip / 3b / sqz

VPIP, PFR and 3bet is enough to spot the weaker players and having a rough guess about their playstyle. Important: Pay attention to the samplesize. Have seen lots of hands post where villain play 40 /20/15 but over less than 50 hands which doesnt tell enough. And since players at NL10 either just try out the game or move up fast, we wont have too many metagame situations.

Thanks everyone for advice and suggestions! Am trying to take notes for what I'm wanting to know during game. For example vs regulars where I have several thousand hands on, I'm finding ft4bet useful, also 4bet vs hero, since I have pretty high 3bet% and they are adapting I think. So I do agree with you Disharmonist that a lot of NL10 players are either just trying it out or moving up quickly, I'm still finding some degree of metagame, and even a significant amount of 4bet/folds.

Thanks taaazz for sharing your hud. Is fold BVB only for situations where V is BB facing a raise from SB? Or also V is SB raiser facing BB 3bet? I find "fold to steal" is a stat that conveys a more general feeling about V in BB/SB vs late raise (CO/BN/SB). I like the fact that you have all positional first in stats. I only put ep-mp-bn but I'm finding myself using the popup for CO and SB stats.. Will consider if it's worth the space.

I had ft3bet but I ended up dividing it into ft3bet ip and oop. I find there is often such a huge difference between those stats (like 30/70), that some players I will never 3bet bluff when they are IP. I guess some players have integrated positional awareness to an extreme where they automatically fold when oop with marginal holding, regardless the 3bet% they are facing or other factors.

Also for the 3bet stat. I have 3bet and 4bet but I find that 3bet doesn't tell you much. A lot of players are 3betting something close to 10% in sb-bb and almost nothing everywhere else, so IMO an overall 5% 3bet isn't telling you much, I'm always using the popup. I think maybe I'll try a 3b vs steal stat, or 3bet bn/sb/bb if I have the space.
