Last season when I concentrated on next season's car, I was getting 1% on the current season, and 7% on next season's car, and vise versa if I flipped it fully the other way.
This season, When I concentrated on this season's car, I was getting 2% for both. I just flipped it fully to next season's car, and now I'm only getting 1% increases.
I've flipped it back to concentrating on this season's car fully again, to see if the result varies, so I can update this tomorrow after the next design update.
Is anyone else getting results like this? Or should I be posting this in the bugs section?
