Said it before and I'll say it again: I would rather have a 37 second course that is fun, challenging, and flowing over a 55 second course that sucks because it's a wadded up mess all day long. The lot invites courses to be lots of 180 degree S bends and corners, and those get boring when you have a course full of them. So darty action is always nice, and I think you accomplished that well.
If you want some crticism, just remember the "slalom" issue at the beginning. Also, your course was VERY fast for cars under 300hp. After the first couple 180's heading back to the corner, I was on the rev limiter by the middle of the walloms. Should have shifted to third like Mr. Sexton was doing in his car. I can only imagine how much longer I would have been on the limiter in an STX Twin. Also, was shifting to third before the finish. That all having been said, I never ask to design courses because I have no idea what I would have changed. We already had a boo boo on a Corvette because the walloms clearly weren't flat for him :/
So, not a perfect course, but really, really good. Especially for your first try. It wasn't my favorite that we've done there, but top three easily Gordon's course with the walloms from hell at the end a couple years ago (when we set up in the rain) was by far my favorite haha.
