Okay. I've improved and optimized this solution enough that it's time for an entirely new set of notes. Min MechA. If it's not I'll eat a tissue. Video proof. This is my first foray into the MechA world, and I think this was a great puzzle to get used to the idea of the metric without requiring... some of the things I know MechA can require. My initial solve used the same 2 atom block waste chaining but was much less efficient with its use of area. The layout is basically the same in concept with small tweaks. Area improved from 140 -> 115 -> 101 -> 93 -> 89 -> 90 I predict this solve will get 19th barring a catastrophe. Additionally, I predict 1st manages to re-use the waste in the next product instead of chaining it away, saving around 10 area but using more in the process. So I predict 1st is somewhere around 82 area. Edit: Sadly I accidentally used a swing that added 3 MechA in my last solution. Fixed, at the cost of a single Area.
