A couple hours work on my first day of solving the puzzle.

This solve is heavily input-constrained, being 8R when the rest of the solve could pretty easily be made 6R. However, input and berlo are just so awkward to work around that I couldn't find any <8R Input Handling Method. Knowing this crowd, someone's probably found it though.

Latency feels alright, maybe you could shave a couple cycles to get around 60C. Don't see it getting anything below that before the <8R solves.
