Nice and simple tape trick. Good one.

It occurs to me that GF could do this in software, and create a perfect map of each GF. It’d be a pretty simple process - put in a full sized piece of material (paper, draft board). GB scores a grid (or at least a known set of calibration points) on the material.

You don’t happen to forecast stock prices too, do you?

No, but long ago in my career I did write software to calibrate scanners by scanning a reference grid and generating a correction map so that future scans came out correctly. Correcting for optical distortion by using a reference grid is a very old technique, and very well understood.
