I do have a steeper throttle curve dialed in my futaba 8fg. The Castle ICE 100's I run are a little smoother and run cooler.
It's probably not that the endpoints drifted, it's just that the battery voltage drops which affects the idle setting. If you had the motor constantly spinning before takeoff and then it's stopped when you land, if you wait for a little bit it will probably start spinning again as the voltage level rises. Castle's do the same thing.
