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" ...

Paste is a robbery, not a standard job

Part 2: Standard Jobs Relevance Update

Standard Jobs have quickly fallen out of the meta: they give little in terms of money and their slightly larger rep gains vs robberies have been overshadowed by rep gained from attacking and reviving. With the new production prestiges increasing the value of having rep, this a good time to make them relevant again.

To begin with, all current rep gains from standard job will be increased by 50%. Additional increases will be added through cartel perks and university courses for up to +400% gains (all perks will be additive).
