It seems to vary for me too, but I never actually timed it. I can say though, if you're running the 4 lapper, or better yet, one of the 10 lap LeMans races, buy the agent. Don't skip it to save 1 GC. The game return will more than pay it back.

Actually, you still get the 70%, just not the 100% the agent gives you. Still better than nothing.
