I'll chime in to say that I more recently started ramping up my online play, and I managed to pull off a clean and consistent FIA Manufacturer's race at Maggiore. I went from Sportsmanship B straight to S! Though I was happy to have the opportunity to race against cleaner drivers, I don't really feel like I was qualified by that one great race. Don't get me wrong, I have no intent of cutting corners for my benefit, hitting cars on purpose for any reason, or swerving across the track to defend, but that doesn't mean I'm experienced enough to not miss my braking point and hit someone, or misjudge the grip I have in a turn, and slide sideways into someone. It's hard to judge in the moment if I have a good overtaking opportunity, without more experience than I had when I got the rating. I will say that I have improved in a lot of those areas, and have maintained the S rating for a while, except for briefly dipping into A and back up again.
