So, I've been wondering whether an educated assumption is correct. On Route Management pages you obviously get the cents per ASK/RSK metrics and these are colour coded through red, yellow and green.
How are does the game decided these colour coding? I've found nothing on the subject.
My educated guess is that it turns yellow roughly at the break even point. I've done some napkin math by divided costs for a month by the total available km's for each metric and it's close enough to look like I could be correct.
The colors are not that smart that they'd go behind the data of every route and their costs, but change statically based on what the value is.
