Sooo ... I decide to test how "Standard Job Rep" work. And it didn't, according to what I see. 

First I do "Coca Paste Robbery" without this perk ... and as you see I get 78 rep!

Then I push the upgrade. If my logic is right ... usual standart job now must give something like 98-100 rep.

As you may see ... I do another 2 same jobs ... and get 79 and 77 rep!??!?!?!?!?!?!

So the question is: Do I do not understand something ... or we have a bug here?

i think its for cartel mission rep i think? could be a bug

It says "Standard  Job" ... not "Standard Mission" ...
