Honestly, until about two hours ago i'd assumed that surely min period for basically any puzzle is 4. Messing around with this made me suspect that wasnt the case, and then some research showed me that its actually not even that hard to do P3. While I don't really know the game well enough to specifically optimize for area here, this feels like a decent shot at it. I didn't want to think about what waste management looks like at P3 so I aimed for a no-waste solution from the start which hopefully helps
