After finishing my area solve I thought that I might be able to just add another arm somewhere and drop the cycles for a decent sum solve, and I pretty much did that and then optimized with a few different layouts. No I didn't use any pistons.... cost is already the biggest factor in my solve, I'm alright. Hopefully this is alright, I'm not experienced in sum. I have no clue what min may be. It's probably like -5 or something.
