Nut flush vs possible FH on the river

Ok after thinking for longer about this hand, I conclude that villain's range at river is...

95 (6 combos) 55 (3 combos) Q5 (9 combos) maybe Q9 (6 combos) and all flush combos (I count 28), and bluffs.

So, we beat 37 combos and lose to 15.

Obviously I'm assuming that his pre flop stealing range is ATC, based on hero's read.

This is such an easy shove, since he's calling all 28 of those flush combos the vast majority of the time.

If he flopped a set, then that's tough luck for us, make a note so we know in future he can slow play sets on this flop. If he has 55, then make a note so we know he can call flop bets chasing 2 outs (or is that one?). If he has 95, then it's a cooler.

Did I add the combos up correctly?

*edit - I missed out overpairs in his range. Not sure he has them after flatting flop bet, but if he does, it obviously increases our equity.
