>>> It's a little more complicated than specifying a certain %, because the "percentage" contributed by hands, hips, etc will, in reality add up to greater than 100 per cent. However, if we were to use a less scientific & therefore less precise model for the sake of making a guesstimate, then these are the numbers: hips, 60 per cent, upper body, 40 per cent. Of the 40 percent attributable to upper body, about 45 % of the 40 % would be shoulders/triceps, etc, about 45 % of the 40 percent would be arms & hands, and about 10 % of the 40 % would be wrists. About 2/3 of the 45 % of the 40 % that = arms & hands would be arms, 1/3 hands. So............40 % x 45 % x 2/3 = 12 percent being the aproximate amount contributed by the hands.
Margin of error for this guesstimate is plus/minus 1/3...that is, hands could easily contribute as much as 18 percent or as little as 8 percent. <<<

Hi J

You estimated that the hips provide about 60 percent the power for the swing while the upper body provides about 40 percent. That may be true, but I would like to make an important point by asking a follow-up question. – About what percentage of the power for the swing would come from the hips if the batter kept his shoulders closed?
