You sure that thing is not estimating your 1/4 mph? I would bet that is what is going on. The tracks all estimate speed and I would assume the same here. The times are pretty terrible for those mph if it is 1/8 mile mph. (not trying to flame, but thats the truth) I have slips of 15.5 at 85mph (damn headwind) The 60' is high too, a 2.2x is about the best NA tour runs w/o drag radials. So your .2 slow from the start.
