Speed (Centrifugal Pull) and Prestress (Acceleration) stiffen the Clubshaft for consistent (minimum to maximum) resistance to Impact Deceleration. Treat that “heavy” feel of “Clubhead recover” after Impact as though it were all Impact, even though the ball is actually long gone. 6-C-2-C IMPACT CUSHION The prestressed Clubshaft will resist the added weight of the ball during Impact, instead of the cushioning the impact with an unstressed Clubshaft. See 2-M-1. Clubhead Lag Pressure normally remains constant regardless of the Velocity it has produced. And both #1 and #3 Pressure Points are the product of Accumulator #1. 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.
