The factory tendency at Minneapolis NE is shown as +68%.
The occupancy is shown as 46%. Now calculate the effective occupancy last hour: add another 20% because of capacity growth, then double it because of moonlight, so actual occpancy to be used in the calculation is around 130%. That should give growth tendency of 16% on express.
This isn't endgame, so investment clicks aren't all that many. I think the ones before recalc don't count in the displayed tendency? So it's just my invests this hour (2) for another +0.8%.
It's well short of the +68%.
Further evidence comes from the transports. We're now only two hours after people started running sheet metal. Total transports of 10,500 tons. The capacity is 4000 tons, it's not even enough for 50% growth when delivered in a single hour on Express. It was delivered over two hours, so the growth should be even less than that. But the factory is level 2 and 63% - thats 160% growth.
I've attached pictures of two other sheet metal factorys which grew significantly last hour.
