I can't imagine being where I'm at today, or having had made the progress I made early in my poker career without HH analysis and stat analysis etc. There's just too much information you can get out of it, that you're leaving so much on the table by now doing it imo.

My best advice is that as soon as you get a big enough sample of hands (>150k hands or so), just run filters. A TON of filters, in every type of spot. Figure out if you're more profitable flatting BVB in BB vs 3betting (remove nut hands like AA/KK/AK etc so that you're comparing flatting mediocre hands vs 3betting). Figure out the profitability of flatting SC's IP vs 3betting. Figure out your profitability of flatting mediocre hands in blinds vs 3betting .. etc etc.

I guarantee you will find at least one thing that is very surprising. One spot where your win rate is WAAAAY larger choosing option A) vs option B), which makes you realize that you need to be doing that option A (whatever it is) a lot more.
