Course stats:

Length: 0.73 miles (1.18 km)
Average Speed: 43.0 mph
Max Speed: 59.9 mph
Max Lateral g's: ~1.05 g's in both directions
Max Longitudinal g's: 0.396 g's under acceleration, 0.730 g's under braking

Video link to my fastest raw time (61.587 + 2)

There really wasn't anything terribly interesting in the analysis of the course data. I found a bunch of places where I could have gained time and it was mostly in the slower slalom sections where I wasn't being aggressive enough with the wheel. The main reason for that was the fact that I was chasing a very loose car the entire day. Jeb rode with me during my first run and I believe he can attest to that as we were fishtailing all the way up the taxiway.

One thing I did note was that I reached my max speed at 3 different points on the course. The first was entering the 2nd slalom on the taxiway, the second was entering the big "V" on the main runway and the third was crossing the finish line. My rev limiter kicks at 61.4 mph and it was almost comical that I got so close 3 times but never actually hit it. Well, I technically did hit it at the end of the course but it was after the actual finish line.

Just for grins, I put a marker in the middle of the sweeper in the crossover section to see what the average speeds were for each half of the course.

Course length for the taxiway: 0.4 miles
Average speed for the taxiway: 40.5 mph
Course time for the taxiway: 35.95 seconds

Course length for the runway: 0.33 miles
Average speed for the runway: 46.6 mph
Course time for the runway: 25.48 seconds

If I get some more free time, I'll revisit the "2 second cone" from the other discussion.
