Can autocrossers take advantage of data analysis? Of course. And easily, too.

There are plenty of excellent data options for today’s autocross enthusiast. In addition to the autocross-centric SoloStorm suite, both the Apex Pro and VBox can be configured for point-to-point runs.

So let’s compare two drivers in the same car at …

Figure 6 is interesting though.  For a typical autocross, that straight away out of the corner is hardly seen, so it looks like it works out for you in this case but would have been bad if this was a more typical autox course.  I always struggle with these two choices though so data certainly helps if you have time to go through them between runs.

I'm still just in awe of the venue.

Yeah that was definitely one of the more intriguing spots on the chart and I think it really sums up the comparison very well. Bret was driving on familiarity. With the car, with the course, with the characteristics of the site. I was just sticking to the basics, which pretty much means late apex everything, get your turning done early and find as many straight lines as you can. I was almost approaching it more as a road course than an autocross course. So in that sequence, he was faster getting to the apex but I was faster leaving the apex and it just happened to be a corner that rewarded my approach a bit more because of the long subsequent straight.

Another thing I didn't really get into much was total distance traveled. My runs consistently covered more distance than his. Not by a lot, and honestly not by as much as I was expecting, but he was definitely driving a cozier line everywhere while I was trying to open everything up. That approach really cost me in that one right hander early on where my desire to increase radius got me out into the marbles. When you look at the actual track through that corner, Bret is on a line I never would have even considered. He just cut a ton of distance and drove point to point. He basically put a couple autocross maneuvers in the middle of the track-style stuff and it paid off for him big time and hurt me big time from not realizing just how bad things got when you got off line.

Bro it was so much fun, even though you absolutely smoked us all weekend.

For the record, Saturday raw times put me in 7th and Bret in 12th (with cones). His raw time put him about .6 ahead of my best raw. Sunday Bret was 3rd overall and I was 4th, again about .6 apart. 

Rob, however, put the wood to the entire field, dominating raw and PAX both days with no one coming within like 1.1 seconds of rim in raw time and crushing PAX by over three seconds both days. I was fifth overall in PAX Sunday, SIX SECONDS  off of Rob. Just absolute god mode driving.
