I'm sure you and I are aligned, but what I initially said in this thread is that saying things like "increasing the speed is more important" is misleading. Thousands of internet readers currently believe that a "lighter cue is more advantageous than a heavier cue because you can get a lighter cue to a higher velocity... because increasing the speed is more important."
That's what I'm saying. Physics-wise, a lighter cue and its resultant "higher stick speed" is not inherently more advantageous. But lots of forum readers will swear by it because they misunderstood the "velocity squared" concept, and they'll cite the kinematic equation is proof.
