I have a theory of what this is. But can someone explain please?

It is a overlay showing the position of stitches shown at different mm sizes over a set distance, but no idea of why anyone would want to use it

If you start marking out your stitching at both ends of a straight run, you will likely need to adjust the distance between stitches near the middle so it looks like they are evenly placed instead of having a very short stitch or long gap.  It also works if you mark from one end, you can adjust the spacing at the opposite end to make the stitch lengths fit nicely.  Looks like you just lay the template over your stitch line to mark the remaining stitches.

If you go to the link YinTx posted you can see how it's used.  Nice clear graphics.
