I've taken some time to poke around, verify, validate, and run through some scenarios with it. It's a very useful tool! Thanks for making it.

There's a small bug in it where neither side's autonomous ring gets a peg score (e.g. putting the autonomous ring on the top should net +15 points at the end). While there's no clear wording on this in the manual ("autonomous rings are like normal rings except"...), both the animation (at 7:14) and the game manual (part 2, page 14) confirm that they are scored like normal rings. It's a simple fix to column AH, but the sheet is password-protected so I can't modify it.
