I just used solver in excel and set up Hero's Value Bet/Bluff ratio based on bet size. Standard (x+1)/(2x+1) where x equals bet size in relation to pot. Once I had these inputs set, I created a total expected value formula basically just the weighted avg of the 7 different scenarios we could have (Hero Nuts Villain Nuts, Hero Nuts Villain bluff catcher calls, Hero Nuts Villain bluff catcher folds, Hero Air check, Hero Air Villain Nuts, Hero Air Villain Bluffcatcher calls, and Hero Air Villain Bluffcatcher folds). Then just max our EV by changing x and I also got 1.236X as our optimal bet size.
All my formulas were linked but I basically set our valuebet/(value bet +bluff) percent to make villain indifferent to folding or calling when he had bluffcatchers. With our 1.23X bet size our value bet/bluff ratio was roughly 64:36. Given that we have the nuts 33% of the time, this gives us a P(bluff given we have air) of 27.2%. Different than the 17.6% you mentioned.
Your math is good.
I should've said 27.2% there, my bad. I'm not sure where I got the 17,6% from, I should've double checked.

Appreciate the replies in advance, I'm a noob here so I am probably overlooking something obvious.
OOP's calling % changes the EV of IP's bluffs. OOP has to make sure, to make IP's bluffs indifferent, just like IP has to make sure that OOP's bluffcatchers are indifferent when he bets.
Therefore, if OOP doesn't want to be exploitable, he has to make IP's bluffs exactly 0EV.
And he does that by folding 1,25/2,25 = 55,6% of hands. Which means he has to call 44,4% of the time. 20% of that are nuts hands, and the rest (24,4%) are bluffcatchers.
Therefore, when he has a bluffcatcher, he calls 24,44% of the 80% of the time he has it, which is 30,6%.
