I have heard that the Excel formula exists and requires the trimmed shaft
weight (in grams), shaft length (in inches), weight of the head (in
grams),
the grip weight (in grams), and the fulcrum point from butt end of the
grip
(14 inches) of the finished club to produce an accurate swing weight value
forthe club. It gives the swing weight prior to full assembly which is
really the best time to make adjustments.
