[Martee]

Martee, I can take a normal grip of my GW, put the head under a big table and easily make it bend the needed 1.5". So, the needed forces are small.

Somebody posted a good pic about droop in rec-golf long time a go - you could clearly see how sweetspot and handle are aligned, thanks to droop. Could probably google it up, if you want.

Seem it was just some fog about diffrent plane lines, after all - thanks, Yoda.

Just a note - Your test you performed was testing the stiffness of the shaft. Long time ago, there was a similar method used to measure shaft stiffness. Lock the grip end, apply a weight to the other end of the shaft and based on how much it 'Deflected' that would then determine if it was a stiff, regular, etc.

Droop is a function of the stiffness of the shaft based on the forces being applied through acceleration. The Major force will be CF.

It might be easier to see how much it has to deflect by taking a dowel and hold it along the sweetspot plane angle and then picture what this has to be at impact and what it would do for a given swing plane/angle.
