Rondavu, good point. there's certainly more than one way to scale a fish. However, in the end you're doing what all good players do, have a system and execute it. The real (or actual) difference between a good player on a $25 or $200 NL table (or a $20 MTT) and a good player at the highest levels of poker is that difference in how complex and experienced the system is. A simple TAGG (or even nut hunting) system works at some levels. But for that kind of game you're working on and aspiring toward, you need a very complex, textured, "aware" game. Keep at it. It's a worthy goal for sure.

The reality of why other players stop on one plateau or another before they reach that highly textured and "aware" game is Laziness. It takes so much work and anguish and dedication and strain to move up in skill that most players say screw it. And there are, IMHO, 3 levels of poker players: fish, Winners, and Elites. I hope you become an Elite. It sounds like you're putting the work into it.

good luck
