adjusting AI aggressiveness in game setup

[wit>trope]

When you setup a game you can adjust the AI aggressiveness from Least Aggressive to Less Aggressive to Default and so on. Default gives the normal variation in aggression levels for the different civs. I was wondering if you select, say Less Aggressive, does that reduce the aggression levels for the different civs by the same amount while keeping their variation or does it just set the aggression level for the different civs to the same lower level?

Least/Max Aggressive=all Civs have the same level of aggression (FWIW).
Less/more: All Civs +1/-1. Note this has no effect on those Civs that are already at 1 (for less aggressive) or 5 (for more aggressive).

Thank you SO much!

If you win say Emperor on Least aggressive, does it take the same skill as normal aggression with Conquest victory condition enabled?
