Over-Acceleration means what?

6-C-2-D LAG LOSS The very small degree of Clubhead Lag permitted by Clubshaft Flex, makes this procedure especially susceptible to Clubhead Throwaway. And the stiffer the Clubshaft the less the margin.

Over-Acceleration is the menace that stalks all Lag and Drag. Here it allows the Hands to reach maximum speed before reaching Impact and so dissipates the Lag. So the length of the Stroke and the amount of Thrust should be adjusted and balanced to produce a “High Thrust-Low Speed” Impact – “heavy” rather than “quick.” Daintiness is dangerous.

Ideally, the rate of acceleration will remain constant during the downstroke and impact, which means that the Hands have gradually and evenly increase speed from top to bottom. The rate of acceleration will be constant, if the sense of pressure points pressures remain constant. If the Pressure Points Pressures change, then the Rate of Acceleration has changed.

So, keep the pressures on the pressure points from increasing or decreasing during the downstroke.
