Imo
I dont think so.
my definition of accum #3 is the rolling of the left arm accentuated by the left shoulder turn. This is passively felt at PP#3.

When the angle between the club and left hand is zero, I feel no transfer of power at PP#3 simply because as hard as i might roll the arm it does not rotate the clubface.

Holding the club along the lifeline of the palm makes it very difficult if not impossible to rotate that clubface.

This has been a source of debate in older posts.
