The in the elbow is "in" the easier it is for it to go into pitch position, the more the elbow is "out" the more it has to get back in to get into pitch position.
Go look at a swing sequence of freddie, he has a deep pitch elbow position even though he has a BIG flyn' elbow.
BUT
Watch how far that elbow moves from "flying" back to an "in position" before the rest of the downswing happens.
Could the distance involved in moving from the flying elbow to the pitch position contribute to more speed?
