BSF

BallSack Factor
The BallSack Factor is calculated by the difference in the height of your balls divided by the length of your lowest hanging ball. The difference of the balls is measured from the center point of the upper and lower ball. The length is determined by measuring the distance between the base of the ball sack to the lowest point of the ball sack.

BSF = Δballsack / ℓ ballsack
