If Y is the scaling factor, x1 is the baseline, n is the scaleup, and a result of 1 is perfect scaling and 0 is no scaling at all, then.

Y == (X - x1) /  (x1 * (n - 1))

Example...

  • baseline is .5 (x1)
  • scaling by 4x (n)
  • If measured is 1.5 (X), then scaling = (1.5 - .5) / (.5 * (4 - 1)) = 66%
  • If measured is 2 (X), then scaling = 100%
