I think the RS4 time is from a spring test.

You are absolutely right: it is a pretty complicated equation, which is exactly my point. It is difficult to know how the weather (and other variables) will affect different cars. So, I really do not see the point of comparing these numbers and claiming a 10-15 second difference is significant in one way or another.
