Ok, I get the picture: so what you are saying Geoschmo: always take 120% in maintance reduction!!! (if in a unmodded game), because it saved you 80% of the maintance.
But is this also true for other race traits, like research, trade, miniral extraction etc.
Because then this will open a totally new window for me: I really thought that upgrading from 100 to 120 % maintance reduction would give you 4/5 maintance instead of 5/5.
But WHY did they do that.
It would be more logical to do it the following way: maintance(25% of value ship) * (100 % / race trait maintance reduction).
