Wow! Choosing Bill Nye over Mr. Wizard really shows how young you are. What is so hard for you to believe that he did 108 when you did 109? Yes photos can be chopped and people can lie on the net. The way i figure it (I am no engineer) is that the faster you go the bigger the difference will be. Kind of like a curve. Another way to put it is if you car does 20mph, then +-1mph is consistent. If your car does 60mph, then +-3 would be consistent. But as it has been stated before, If you don't have anything productive to say, then don't hit the post button and move on.
