Dimples on a golf ball are symmetrical, therefore the effect of air pressure is predictable. If one could predict the effects of random occurrence (grime on a car finish, for example), that person could play the lotto and win every time. Random occurance is the angst of statistical analysis. . -- haunyack Transporter -> B&K Reference 200.2 -> Vandersteen 3A Signature. RWA (Analog) SB3 -> Rotel RB 1070 -> B&W Matrix 805.
