Hello -- I played through the 8th stadium tracks, got a silver on my first run of the 8 player track (but still top 4 against the AI opponents, so moved on), and after finishing the 4 player run and the duel to close out the stadium, I went back to the 8-player run to get gold. The opponents don't use their default times / ghosts any longer and I cannot come close to the top 4 positions. Even though my run is finishing 8-10 seconds faster than it did the first time around, I'm 6th in finishing every time and since I didn't "beat" the level, my time isn't saving and I do not get the gold medal upgrade.

Thanks
