BHE/FHE Techniques

Bob Jewett said:
The angle of swerve is given by the same method that Coriolis described 173 years ago for aiming masse shots. Your stick at the instant of contact with the cue ball points to a spot on the cloth, X. The cue ball at that instant rests on a spot on the cloth, Y. The final path of the cue ball after it curves will be parallel to the line joining Y and X.

Is the spot X more "to the side" for draw or follow?

I'm not sure...

I would guess that if we shoot a draw shot with the tip of the cue pointed at X1 and a follow shot with the tip of the cue pointed at X2, AND we use the same amount of sidespin on each shot -- then line X1Y and line X2Y would not be parallel. Line X2Y would be closer the line of original aim of the cue.

Does that mean that all other things being equal, the angle of swerve is greater for a draw shot than a follow shot?
 
draw final swerve angle is large than follow swerve

Yes. If you want more details and illustrations, see my March '08 article.
