What grinding rate do you think it SHOULD be? : granturismo

Even after patch 1.08 the most efficient grinding methods are above 700,000 cr per hour, so I don't see 1m/hr as a notable improvement. Remember this is pure grinding gameplay: doing the same event with the same car over and over with smallest possible breaks inbetween. Doing that for 18.5 hours to buy one rare car (McLaren F1) can't be the way.
