I used 60 degrees of accumulator #3 as an easy way to get to 90 degrees given the addition of wristcock. Let's make sure we are on the right track here- I'm not saying anyone was at 60 degrees nor did I measure if anyone was at 90 degrees- it was all in the discussion of 90 degrees of wristcock or 20 degrees of wristcock? I've clarified why it's not 90 degrees of wristcock- due to whatever amount of #3 one has. And as the wrist moves through bending and arching- it doesn't stay in-line with the forearm so therefore it also affects the clubshaft relationship to the forearm/arm. I'm just discussing the general idea - not worried about any particular degrees.
