I really like the waste management. However, it only works if the main trackloop is of a length that is coprime to 6. Multiple arms on the trackloop of arm 3 need to be spaced apart by at least 1. This means that the main trackloop is of a length that is not prime. The best length I could get is 17. Unfortunately, 17 is prime, 18 is divisible by 6, 19 is prime, so I was forced to take a 20 length trackloop, adding a few hexes of shame. I was so close to shaving these few hexes off, spending more hours on that than getting to 80 area. Unfortunately, I couldn't find it.
