Damn you! I'm too lazy to get behind the wheel again!
The funny thing is that on a whim, I changed my feedback from 3 to 7. In the past, more feedback always made me slower and initially, I was. Then I remembered an earlier conversation about how much you have to turn the wheel with this GT-R. Once I beat that into my head, I not only had more consistent laps but after a few minutes, beat my personal best. The downside is that trailbraking was much harder to induce and my wheel kept shifting all over my desk. Otherwise, a 21.9x is definitely there for the taking.
Still, it's a shock to me that I was that fast at that high a setting. I need to try this in the later rounds.
