But I just noticed another thing : when I take a level 0 building for example and click on the upgrade button, then in the description of the upgrade, the "normal" profit is displayed (instead of the current one) plus the profit earned after upgrade.

I checked for 2 buildings and the ratio is always 1.4949 for me.
