I like this article, but what about autocross testing? How my region runs it is a practice day (limited runs in a similar format to competition day) on Saturday and competition day on Sunday. We also get a large group of people coming out, so runs are limited and we do not have access to a skidpad. It's difficult to do any sort of usable testing given that you are only given a limited amount of runs even on practice day.

This would definitely work for something like an HPDE where you get 20 minute lapping sessions, and one of the local organizers gives you 1.5 hours of open pit run where it's 1.5 hours of pure lapping, get on and off whenever you want. But as far as it goes for autocross, at least how it's run in my region, it's nearly impossible to get a good test session out of it without missing runs. 

How would I mitigate this?

B) Don't use a jack stand to support vehicle

The article is great.  The pictures showing bad practices, not so much.

If you're just changing wheels I don't see the problem. Obviously you don't crawl under the car, and I'm the super cautious type who throws the wheels under the car with the jacks as well as the extended jack (if there's room) while I'm under it for any reason... but if I'm just rotating or changing wheels, no need for stands.

Thats a great question: how does this work when you can't book a venue for closed course testing and you have to fit it into existing events?

One other wildcard, with Rallycross there are even more uncontrolled variables like changing course conditions, course changes, etc.

Jack stands were present, and one's behind Dave in the opening shot.
