[12 piece bucket]

I read through the archives but I still cannot fully understand the #3. If zero #3 place the grip in the cup of the hand, and acute #3 angle would have a hands low appearance at address, than what energy is accumulated and released?

It would seem that the #2 stores and releases the vertical wrist cock motion but the #3 angle relates to the same plane of motion.

The #3 angle is based on the angle of the clubshaft and left arm when the wrist is LEVEL. So if the grip is in the cup of the left hand you have a zeroed out #3. To obtain MORE #3 angle you would just move the grip more under the heel pad with your Left Wrist in the Level condition. So #3 is STATIC. It is the angle you try to roll through. So at impact you are moving from cocked and uncocking to the Level condition set up at fix and thus your #3 angle of the shaft and left arm. Setting up MORE #3 angle requires more hands speed. This is why Preacher Poke Chop advises place the grip JUST under the heel pad. Setting up LESS angle to be rolled through . . . Less is more in this case.

Note: Players that set up with "low" hands don't necessarily have a sharp #3 angle BECAUSE the #3 angle is based on when the Left Wrist is LEVEL. Not Cocked as the "low" hands set up necessitates. You can certainly set up with "low" hands (some can argue advantages of this set up). Then just move from "low" hands to Impact Fix to determine the true #3 angle when your Left Wrist is Flat Level and Vertical to the ground at Impact.

You are trying to roll the #3 angle through impact. After impact #3 would be zeroed out when the left wrist is fully uncocked to Full Lever Extension.

So #3 is TRANSFER power. You are TRANSFERRING the velocity from the #2 uncocking into the rolling motion of #3. You roll the residual uncocking speed (remember #2 is the Velocity Accumulator) into the ball.
