109 prop pitch (rpm) and the supercharger

Yes, yes. but i really think that Crumpp has a point in this thing.

as with car and transmission example where you did'nt have the perfect gear ratio. Its hard to have perfect pitch with Bf109

As with manual prop pitch when you change the angle of attack to most efficient at that point, plane speed will change because of this and angle is not efficient anymore. Meaning you need to suffle pitch to opposite way to get more efficient pitch and again because of this change plane speed changes and the angle is not the best anymore. You would think that after while suffling pitch forward and backwards you would hit the sweet spot, but because pitch controller changes engine RPM also that means that engine power output changes as you change you pitch, technically you got more boost from the engine before you coarsened the pitch but if you had'nt coarsened the pitch, you would have started to lose efficiency because you have too much RPM. This could make them jiggle the proppitch and as with the rookie pilot that was falling behind he just could not keep the engine at the sweet area and was falling over from there.

---> BTW you can hear pitch change of the planes when you change pitch. I noticed it with Hurricane 2 pitch version in game.

Edit: My head starts to hurt thinking this prop pitch thing.
