I'm not as good here as the outer loop, but hopefully this still helps.

I'm REALLY rusty with the driving physics of GT Sport and the game shows conflicting times on the leaderboard, but this is the first Time Trial on any GT at my best track as far as I can remember so I will probably try to gradually improve over the next 4 weeks and maybe just maybe have a chance to finish #1 worldwide.

Other issues that have not effected me but exist are accolades not giving rewards, convoy glitches, and worst of all progress being lost.
Luckily the devs have said they are working on fixes, but who knows how long it will take and how effective it will be.
