So then if AA placards t/o power MP = 35.3" then that is what we use in the equation for MaxMP when calculating cruise HPs, correct?
The AA data from their table however correspond more accurately to the formula when you plug in 37" as MaxMP.

Sounds like they may have forgotten to include the exhaust back pressure effects in their calculations. Not sure how they got their numbers.
