Is any of this worthwhile?
I just did a test of the default setup (one size fits all) against one that only had the cambers, pressures, and gearing rough tuned. It was a blind test. That is, I didn't know I was running the default. Truth is, why the favorite wasn't loaded is a good question, but it was online and damn near anything happens online.
I instantly felt that the front was understeering extraordinarily but soldiered on. After a couple of timed laps, I'd had enough and went into the garage to discover the favorite hadn't been loaded. Loaded it and had just enough time to get one timed lap before qualifying was over. Moved from the middle of the grid to 3rd. Out of 22 drivers online, that matters. Online you need to be in the front rows. From about row 3 back to the last couple of rows you might as well log out. You're going to be hit unless you've got a couple of cars behind to take the shot, or you're far enough back there won't be but a couple behind you.
I got no idea why those guys don't figure it out. Cars further back in the grid have longer to accelerate and need to brake BEFORE the cars ahead brake. Because they're going to be going faster than the cars ahead. whatever..........
