If you think the only qualities of a gto strategy have to do with bluffcatching frequencies and that's the end of the story, you're quite wrong.
Think about these players playing vs a gto bot:
player 1: he is loose and overaggressive preflop, flop, and turn, and calls down with bluffcatchers when he thinks he can beat a bluff.
player 2: he is tight and passive preflop, flop and turn and folds unless he can beat a value hand on the river.
Where are they losing ev to gto? What do their river ranges look like? Is either player making a big mistake with his strategy regarding his calling frequency?
Think about it before reading this:
This is why when you're bluffcatching you gotta realize that you're basically getting back (your call)/1hand. Only if you can beat a value hand will your call show a profit >0ev. The hands that are >0ev have a calling frequency of 100%, while you can basically do whatever you want to with true bluffcatchers and junk vs a non adjusting opponent that has good river bluffing frequency.
Now think of all the betting, raising, calling, 3 betting, check 4567 betting decisions that you have to make and you'll see that gto is much much more than a few indifference equations.
