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 does it do that? If the cones/beams down track are all the same height (lower than the stage beam), how does the extension make the MPH faster? I understand the ET being slightly quicker b/c the distance travelled is thrown off w/ the extension.
