I promise you I searched and did not find this topic.
For months, my Racing Spirit sat at 99%. Can only do 2nd at the 13.1 3-lapper in Catalunya. I run the race evrytime I pass it and never won. It was either 600+ last engine upgrade or dumb them down. I did neither. Then, I joined a team. I passed it again this morning and entered. Instead of the fast bots, the top 4 places were all from my new team. I run and won the race with spare.
Make what you want from this. As for me, that pestering 99% is now gone.
