In fact, in order to get ''full power'' from ailerons on cambered wings, if you want the most power from the combination of both ailerons, the ailerons must move at different rates.
Wrong, for full power you have full deflection for both ailerons and correct the yaw with the rudder. I know for a fact that many full scale planes do not completly correct with differantial ailerons. The same C 150 I mentioned did not because the roll rate was too slow. Fighters almost never use this though moderen computer controlled ones do during the landing configuration.
Sorry, it's not wrong. Adequate, appropriate deflection works perfectly. Yes, when the design of a plane makes that impossible, you've proven that airplane doesn't fit the basic requirement, not that all others can't. And proven that design hasn't got adequate aileron sizing/shape/movement.
Yeah, I should have said, "in order to get as much power available from the ailerons your plane has"....
The reason those full scale planes that can't completely correct isn't a fault of differential. It's just that those planes have stronger reasons for needing it than their ailerons as designed can provide. And what did the designers decide the C150 needed? Differential, not just more rudder. Unfortunately, the C150 ailerons or their linkages weren't modifiable enough. Or it being a real world airplane, the designers didn't have the time or money or desire to go that route to fix it.
