Calculating scope subtentions at different powers

Simple question - I have a Swarovski 3-9x36m scope with the 4A reticle. Per their specs, the subtention from the crosshair down to the edge of the vertical post at 100 yards is 25.2" at 3x and 8.3" at 9x. Is there a special formula to calculate these distances for 4x thru 8x as well? I would assume a linear taper would be too simple . . . thanks.
