Yeah, it appears it was likely wind after all (I was practicing offline and forgot to check the settings/weather). There was no such thing during tonight's race happening - and also I was regularly using the 6th gear yesterday on the oval section, reaching over 210 kph there, while tonight, shifting into 6th was basically useless as both 5th and 6th managed to get the car to 204 or so.
Speaking of tonight's race, that was really fun. I was getting kinda worried during practice and qualification that it would be a very lonely race as soon as you made a slightest mistake, but while a chunk of my race was indeed somewhat lonely, the rest was intense close racing, especially the last few laps spent with
@thomas hartig mostly two wide or swapping places. As I usually tend to be more on the cautious side, backing out of similar situations and keeping my distance from others far too much, this kind of racing is exactly what I need to practice more to gain more confidence around others
So again thanks to Thomas for a great race, and obviously thanks everyone as well!
