I suffer from stiff hands so our handicaps should be close, I'll a bit more than double your pistol times, almost halve your rifle.
I've got short fat fingers that don't move too swiftly, so my dualist pistol technique is a little slow!!!! :-D
With the rifle, I get to use wrist and arm, I so do a little better, best time, or at least the one that I'm most proud of, double tap 5 targets between 100 and 150 yards in 10.15 sec. With big and/or close targets I don't have to wait for the smoke to clear, I just shoot where they are supposed to be.
