I'm trying to improve my discipline in live MTTs since I feel like a lot of my leaks come from trying to outplay terrible donks who think it's against the law to fold pre or raise their nut hands when you're c-betting/barreling into them (lol, I'm a spewtard and I know it).
One of the ideas I came upon was trying to get a hold of my frequencies by studying the positional stats of low to mid-stakes MTT/180-man pros and figure out, in general, what their VPIP/PFR looks like, how often they're 3-betting, how wide their stealing ranges look, etc.
I know there's a lot to be said for table dynamics, situations and whatnot, but I feel that setting rules for myself like "OK, once the antes kick in I'm going to 3-bet about 8% of my hands, with a value range of TT+, AKs, AKo, AQs, KQs, and a bluff range of suited wheel aces and suited connectors T9-54" will give me a good starting point to where I can widen or tighten these ranges based on how my opponents are playing (i.e. nit only opens TT+/AKo+ = tighten up/depolarize, LAGtard raises 70% of pots OOP = widen 3-bet range).
Any thoughts on how to go about this process, or whether or not it's even a worthwhile endeavor? I'm new to taking tournaments seriously and not much of an online player (primary experience is 200NL and 500NL live), so I wouldn't really know where to get the stats to begin with, but I think doing something like this will help keep me out of trouble while I'm getting some practice in.
