What does lowering the index have to do with anything? If you lower all the indexes by ONE SECOND, then the -1.40 under cars are still .040 faster than the -1.00 under cars. If you don't change the 1.15/1.40 triggers then all you've done is guaranteed that no car will ever be re-factored. If you *do* change the triggers by the same amount, then you haven't really changed anything. It's a barometer. The calibration is irrelevant.
