Here is the exact quote:
"The Lever Assembly is seldom more then an inch from Full Extension at Impact".

Agreed, Mike: There is a difference between my conclusion (point of Full Extension past Impact) and the "exact [Kelley] quote" (degree of Extension at Impact). For practical purposes, I believe that my conclusion is valid.

Remember, the Left Wrist doesn't go from Cocked to Level -- then hang around a while -- and later proceed to its Uncocked condition. No sir, the Left Wrist is rapidly Uncocking -- perpendicular Wrist MOTION (4-0 / 4-B) -- and it is Releasing in one unbroken thrust. Even with the Swinger's Sequenced Release (4-D-0), there is an overlapping of the #3 Accumulator Wrist Roll and completion of the #2 Accumulator Wrist Uncocking.

In any event, the Left Wrist ideally is Level at Impact and then immediately proceeds down approximately one inch to fully-Uncocked through the Impact interval. No way does this complete Uncocking take until the end of the Follow-Through (which was Jeff's point).

I don't want to get too far from the subject of this thread, but since you've raised the question . . .

If at Impact, the Primary Lever has only one inch to go until it reaches Full Extension, and if the Left Wrist is Releasing freely, then what is your best guess as to when Full Extension occurs, i.e., how far past Impact?
