Lol. Humble pie can be good for the digestive system occasionally. Mine too is an educated guess, but with some basis behind it. I have a friend who's plane has been clocked at 74mph with a radar gun, (or so he claims). My NexStar keeps up with it pretty well, he noses away from me but only after a good little bit, therefore I believe I'm getting 70 or very close to 70 out of it. God only knows for sure.
