I doubt it will make much difference to the average fan. There will be fewer oil downs which will make the program run much smoother. The biggest gripe I hear from the bleachers is the down time for oil downs. It will cut down on the parts carnage making it more affordable for the teams to compete. Yes there are many teams out there running on the financial edge (not all are funded with a blank check). They will still be running 300+ under most conditions, but will have a little more room to stop.
I think the positives will far out weigh the negative once people get a baseline for the new times & speeds. There is 1,000 ft. data now, so comparing records shouldn't be a problem.
