Hmm, I'm basically working on the opposite theory, his range for betting flop and turn is 100% of the range he calls PF with, which is very wide in both, and fairly unlikely to have connected often (moreso on 1 than 3, but I represent a really strong hand here).

I guess marginal, these are literally the 3 bluffs (beyond c-bets) that I did for 300 hands in the whole session, so its not like this made up much of my play.
