Intelligence and counterintelligence agents search for any clues that may come to light.
Often, this information can come from the incidental and unintentional release of other information.
For instance, during the "cold war" the west knew how many people were in the soviet prisons and gulags.
How?
Well, the soviets released their population numbers. Very accurate numbers, they were proud to say.
They also were very proud to release the total number of voters that voted in their "elections".
Actually, voting was a requirement. And I suppose that if you didn't get your butt out & vote, then a vote was placed for you.
Of course prisoners were not allowed to vote.
Got it now?
Population minus Number of voters = Number of prisoners.
What does this have to do with Prepar3d V3?

But even a V2.6 or 7 would be helpful.
