Let the folks moor themselves in the sea of their own Bowel Movements.

Muscles stretch and shorten. When we have Pivot Lag, we've created a stretch. When the muscles shorten or contract, they pull between each point of contact. Neither point remains a fixed point in three dimensional space. Therefore, when the muscle contracts it's pull is through the length of the muscle, and it pulls in both directions.

So, here's an over-simplification:
Point A accelerates, point B drags and the muscle stretches.
When the muscle contracts between A and B, it decelerates A and accelerates B, even though they both have forward momentum.
Point A has no choice but to slow down.

There is a purpose to purposely "brake" which can change the angle of approach of the right forearm and increase the closing rate of the clubface
