Once you get a tracking number, it should always stay the same. If the tracking number keeps getting updated, how the hell do you know what tracking number to track when you go to track your tracking number? You would need to track all of your tracking numbers just to be able to track the tracking of the orders, and would likely loose track of the right tracking number. In jr. high school I ran track for a little while so I could track this hot girl who never ended up giving me any traction.
