Interesting. I realized that even with brand new plane, I still got delays, shall we avoid using the maximum frequency?
You should not get delays with a plane at 100% condition. However it's possible that, each tick, airplane condition is degraded one step before route calculations are done.
I am running a test on increasing auto-renewal to 60%. How do I know if i'm still profitable? is the renewal fee reflected on the profit report?
No it is not, but it's not hard to calculate. Multiply the number of planes of each type you have by their price as brand new and divide by 5, then add the result for each type of planes together and divide by 728, this is your average weekly costs for renewals at 60%. Subtract it from your "income sheet" value and you get your net profitability after all expenses.
For example if you had 100 A380 planes, your weekly renewal cost will be:
100x450 mil / 5 = 9 000 mil
9000 / 728 = 12.36 mil weekly
So if your weekly profit from your "income sheet" is 40 mil, then:
40 mil - 12.36 mil = 27.64 mil weekly profit (that is the real one)
However the plane renewal costs are not evenly distributed so there will be times when your weekly profit is higher and others lower or even negative.
