I wildly underestimated how hard it is to make a Youtube video, turns out it's more of a 3 day project than a 3 hour project. Because of that, I didn't dedicate much time to this puzzle. My goal was to get minimum rate with a small footprint, and I'd say I accomplished it.

I'm pretty bad at rate puzzles, and I usually end up with an insane area, but tunnel visioning on that problem allowed the wheels of arms to eat up my budget. I bet theres a much better metal debonding method, but I'm happy enough as is. I'm excited to see the more optimal solutions for this puzzle because it's an awesome metric, just not one I'm good at :)
