I was hoping to have an academic discussion about your idea of abstraction, and how we could use it to optimize the game. It appears I'm not going to get it. When the idea is challenged, you're just saying the same thing over and over instead of having a working discussion that overcomes challenges put to the idea. While you assert your beliefs and brag about your experience, the reality is very very different.
You must think I'm totally ignorant and must be tired of repeating yourself. So I guess I'll just leave it at that... Except for one parting comment: If you think you can ignore a train, any active part of the factory doesn't interact with the logistic network, and fluid flow can be consistent at all; you are ignoring how much stuff needs to be processed every single cycle of the game.
