...I think dr. dave agrees with you, but I would need to see an experiment proving that.../QUOTE]
Just a bit of mental masturbation re: the conditions/design of such an experiment:
You would need: an ‘Iron Willie’ type of robot stroking machine with a variable/repeatable speed control, and a precision timed slow-motion video camera to verify speeds/angles, and at least 4 sets of balls: One clean, (for a control), one freshly waxed, one oiled, and one oiled (but dried) and rolled in a bag of chalk dust. The speed vs. deflection angle graphs (multiple cut angles) would be overlaid with chart-lines of various colors representing each ball condition.
