Yeah, the maths give quite a headache... you see, I like fiddling around and maximizing everything. Now, as long as the formulae are merely complicated, this is OK... but these formulae are downright ridiculous sometimes! Why should turning up factory production necessarily hinder Labs Research??? I have more than enough to finance them both, and don't tell me 10 billion people can't operate five factories and five labs simultaenously...
I don't mind if there are a few complications here and there, but for heaven's sake separate the research and manufacturing sliders...
