I think your qualifying time has a lot to do with your DR. For several days I ran sport races with either slow qualifying or no qualifying. The I would pass 6-10 other racers by the end of the race thinking that this was how your DR went up. I was wrong my DR went down. Today I spent almost 30 min on qualifying. I was 2 seconds slower than the slowest top 10. First race I was 6th made it up to 3rd before getting bumped and ended 10th. Next race I was 2nd first quit opening straight away I finished 2nd. My DR went up by 2000 points. Nothing else I did that day had any effect. My SR remains at 99 or S. I think you cant become an A if you cant qualify like one. If you want to win get better and drive faster.
