it was actually 200 feet higher at the end

There were a couple of nearly instantaneous changes in elevation on that ride. When the rain started there was a 100 foot increase @ about 42 miles, then a 100 foot decrease later on. Maybe when the rain finished, don't remember. The starting elevation is about right, from what I know about the elevation of the town center.
My point in posting that ride being that people shouldn't obsess much over these numbers.
