Sustaining lag and hence bend is not a function of swing speed, but of technique (agree), however, magnitude of bend is a function of acceleration as well as shaft flex. Greater acceleration produces greater swing speed unless a countering deceleration occurs prior to impact (loss of lag).

Hmm? Swing speed is a function of Lag Pressure. The greater the pressure the greater the speed. Therefore the degree of bend is a function of Lag Pressure. 6-C-2-0 "Your "normal" pressure will move lighter Clubs faster and heavier Clubs slower...".

But, when in doubt, "high thrust, low speed" especially on shorter shots. High ratio of bend degree to speed.
