You want the Clubhead Accelerating through the Ball.

I'd also say that you need to maintain the Rate of Acceleration. You can accelerate fast or you can accelerate slowly, that is the rate. To maintain the Rate is to maintain the same amount of lag pressure. A decrease in the Rate of Acceleration, though you may still be accelerating will see a corresponding decrease in the Lag Pressure at the #3pp.

Over acceleration "the menace that stalks all lag and drag", is the establishment of a Rate of Acceleration in Startdown that you cant maintain. Slow Startdown, steady acceleration and heavy is the way to go with the heavy representing lag pressure. It'll almost feel like the hands are not accelerating but they are, they have to.

The Endless Belt Analogy is an analogy only, showing the added speed associated with a small pulley wheel, late release.........hand speed can not be constant if you intend to have any lag pressure at the #3pp. It may feel like it but it cant be.
