Power/speed number
From BR Bullpen
Bill James invented the Power/Speed Number, a single figure to quantify the idea expressed in the "40-40 club" or the "30-30 club" and other combinations of stolen bases and home runs.
The formula is 2(HR x SB)/(HR+SB). James himself has referred to this as a "freakshow" stat with little analytical value.
