Factories need tuning then. Perhaps not so much with the levels they produce, but the rate at which it happens?
Currently facility maintenance happens on the daily roll, once per day. I could double both production and the rate of decay by simply running the maintenance every 12 hours, or triple it by running it 3 times a day. Bonus: more chances to collide facilities at different points of the day. Downside: faster decay means vigilant maintenance, but that might not be a bad thing.
