That's definitely unexpect for me. Something might be wrong because in every track I played 2 stops is the minimun. Can you share some screenshots during the race, just to compare the tyre degradation? If you let me suggest you one, try in Austria, and starting with softs. Disable Safety Car just to not interfere in the management. If everything is going as expected, you should stop at lap 4, when the soft tyres are around 80%, and with two sets of mediums reach the end of the race stopping in lap 11.I used the WearGrip folder from version 4.11 i think that's correct? I've attached the race strategy page before my career mode race at Monaco and although Nick De Vries crashed into the back of me and made me retire with a few laps to go i think i would have easily managed a 1 stop after pitting on lap 2. Of course the game simulated the rest of the race but everyone else who didn't have damaged managed the 1 stop.
