The little secret they don't want to mention is that it also increases MPH readings 3-5 mph, so they can brag about how much more Horsepower they have.
How do you figure that? If all the down track beams are 6" off the track the speed will be the same.
Maybe the tire hits the first one and when the front end drops the pecker hits the last one, less time=faster mph, same as et.?? Can't see it happening if down for both.
