* This shape is a cross between a ramp and a double peak.. It starts with a plateau that droops a little, and has a considerable peak about 0.1sec before impact.

** (Specific swings shaded) Corey Pavin (and also Davis Love with an iron) is not only a double; it has the maximum deflection at the first peak, not the second. That is why the "Time: Max Defl to Impact" is so much longer for those swings.
