Comment 22 for bug 571796

I am going to change the conf files (this makes sense independant of the productivity statistics).
A question to the quarry: Would it make sense to have the order worker=cut_stone, sleep=25000? It would then not be consistent with the other entries (where the inverse order is better) and the productivity would drop very fast. The reason is that once all stones are gone, the productivity will never raise again. 0% would therefore be a kind of prediction for the future. It would be a clear indication to the player and maybe also help the AI (I think it uses the productivity to decide whether a building is dismantled).
