Optimised New Solution 2. If you're reading this, that means I couldn't beat my Day 1 stake in the ground. (though judging how the tournament's going for me so far, this might not even be getting read at all lmao)

I suspect 10R is possible given there's space for a whole ass Arm 10, but I don't think 9R can be done. I will eat a cow if theory min 8.4R is possible.
