Over the course of the stage, there are often on the order of 30 waypoints, between speed zone entrance and exits, WPM, WPS, DSS, ASS, etc. The GPS records mileage as covered on the ground, UNTIL you collect one of those 30 waypoints, at which point it sets itself correctly to the roadbook.

So, the advantage of the GPS odo is that it automatically corrects itself. I found myself using it more and more heavily as the rally progressed.

The drawback is that you can't increment or decrement it if you get lost... but the need to do so is mostly obviated by the auto correct function.

A few car navigators I spoke with indicated using the GPS odo more or less exclusively.
