ET & MPH do not tell the entire tale. Post all of the incrementals from the quick run, and a couple other complete representative all-out runs.

Typically, I find that 2 mph is about .01, so you probably got rid of .04. Didn't I read somewhere that there had been a weather shift and a tailwind had come up? It's very easy for a car to move that much in the 1/4-mile. Now, if all of your incrementals are adding up the same, and then it shows a pick up of .05 just in the last 320', then you may have something. Study the incrementals, split times, and speeds.

Also, if you have an uncharacteristically late reaction time, and all of your incrementals come up way fast, it's often a symptom of a stage beam hanging.
