It may help to break up this 75% cbet range. What hands does a TAG cbet, (TPTK+, some complete whiffs, strong draws)? What hands does he check (TPGK, gutshots, etc)?
For now, im doing a base analysis using a loose aggressive (preflop) who cbets most flops and gives up when he's called. Basically your standard unremarkable 25/18ish player.
