I have maybe a differant opinion on this?.. I think everyone knows all the cars are set-up to be on the edge at the 1/4 mile to get the most out of their pass. Shortening the distance is only going to make them push their cars just as hard as before and be ready to let go 320 feet sooner.
So will it help? I am not so sure how much if any. Of course it will slow down the MPH by a fraction.. Any other opinions on this?
