Thanks for your efforts to make all this information available to the end users.
Yes, I intend to get around to the PS 85.

Without looking at the details, my answer would be this: to get the spin window measurements, I measure the frame thickness 19, 20, 21, 22, 23, and 25 inches from the butt. I do the same for the inner width of the racquet face at those locations. So the window size will be location dependent on each racquet, even if they have the same head size and/or thickness.
