Another great metric, you guys are on a roll. I generally dislike area puzzles because there's no obvious floor so I appreciate that bestagon gave a very obvious lower bound (4 + 2 input, 7 output, 2 bonder, 2 debonder, and 2 projection equals 19, ruling out a radius 3 solution).

I was torn between doing one product per period, or doing one product per 3 periods. I ultimately went with 3 because it seemed more fun, not for any mathematical reasons. I have a feeling the most optimized solutions will also be 1 product per 3, but I had a busy week, so I enjoyed making this slightly stupid solution much more than I would have enjoyed using my brain.

I really wish radius 3 was possible, I like it when the primary is extremely difficult, instead of just being a constraint. That being said, these weeklies are infinitely more fun when I remember that I play this game for fun, and not to win. 

P.S. Two area metrics?? I can't place down a spade this week!
