I made an experiment too. Unfortunately with barbarians, since I had forgotten what _aD did.
Construction time of two babarian fortresses increased from 100 to 139 seconds in my setting. The setup mimicked what I remembered from _aD's experiment. I repeated the play few times, and the results hold within few seconds. I would be curious to see the experiment 1 savegame.

I did my timings using gametime.
