Just because you have “GTO Preflop ranges” doesn’t mean you’re not losing more EV than you would if you didn’t use them in the first place. Poker is a very difficult game, and if you’re playing in spots with hands you’re uncomfortable with, bigger mistakes will be made postflop.
My preflop range is 100%, because my coach told me once in a song: Every gambler knows That the secret to survivin' Is knowin' what to throw away And knowin' what to keep 'Cause every hand's a winner And every hand's a loser
