I understand that to mean that the there must be forward shaft lean at impact with a flat left wrist and bent right wrist. I don't think that it refers to wrist positional variations at impact.

My response was to clarification in determining Grip Type for Long Hitter (10-2-B vs. 10-2-D). "In-put-Out-put Power Ratio also is utterly dependent on Hand Location at Impact" was to stress the importance of how the longer Hitters achieve their length and the alignments of Grip Type. I did not mention wrist positional variations at Impact directly, but all of the reference numbers I mentioned can be tied directly with 4-0.
