I was reading my current issue of R&T, the one with the 5.2 0-60 time. A section in the mag. describes how they test for acceleration. R&T does a 1 foot rollout before they start the clock, which according to them the average car takes .03 seconds in the first 1 foot. They also say that they do not adjust times for barometric preasure, temperature or other factors. One of the other mags does adjust for these conditions, I just can't remember which one.
I like their shallow staging procedure, but not adjusting certainly could be problematic. I wonder if all the mags shallow stage. I wish they all would do things comparably.

I think C&D adjusts for some of those factors.
