[Solved] How many TUs do aliens reserve?

[Kzer-Za]

I am thinking of one little mod, and I need to know what percentage of their TUs do aliens usually reserve (on the average) when they do not see you. Perhaps someone could tell it with some degree of certainty?

Aliens reserve time units when in Patrol mode.
They reserve different amount based on their aggression; can be 0% (aggression 3+), 33% (aggression 2), 40% (aggression 1) or 50% (aggression 0).
