I don't know what your definition of "matches pretty much" is, but it's certainly not mine.
Values without parantheses or brackets: Current ingame value
Values in parantheses: Result of official formular
Values in brackets: Result of damped official formular

Out of nine tests, only one test result matches the result of the damped official formular. The deviation between the other test results and the damped official formular vary from 1 to 5 (!) points. That's a deviation of up to 5.88%, definitely not what I'd call "matches pretty much". Furthermore, the damping theory doesn't explain why the largest deviation happen with vostaskus, where no damping should take place (damping multiplier = 1). The most important thing is that both the official formular and the damped official formular can't be explained by Arrakis' version of how it is intended to be.
I side with Davis105 on this one: It seems that we're talking about a bug and not an undocumented feature.
