These USS are quite predictable.
Threat Level 2, Weapons fire detected, most of the time spawns 1 or 2 police + 1 or 2 wanted ships.
They never are engaged in hostilities, so what the "weapons fire detected" is on about I do not know.
The police always ignores the criminals unless the player opens fire.
Also the criminals are very low level morons 99% of the time.
Threat level 2 or 4 USS with convoys mostly spawn a few military ships that fly about doing nothing.
They very often contain a Python with a medical cargo and a few Vultures.
There are a few USS with ambushes, but out of a 100 USS I encountered perhaps 2 of these.
The distress call USS mostly contain a single ship under attack, although it in general is not the distressed ship itself that is under attack but you, when you jump in..
This type of USS is the only one I know of (besides the ambush USS) that can become very entertaining and challenging, if it is one that spawns waves of enemies.
And so on...
I would love it if FD would add a bit more variation, but most likely I have not seen all there is to see yet.
