A key and extremely important thing NOT TO DO when using google maps is have more that two destinations. Using more than two destinations will cause the GPX conversion routine to create a route for each set of destinations. Say a three destination route. A, B and C. A route will be created for A to B and from B to C. When you really wanted one route from A to C. So don't convert a dropped point to a destination if you want a single 'route'.
Also save each day's route in Google Maps as a favorite. That way you can readily look at the route when you are cross checking it's accuracy upon gpx conversion. The only way I know to create a bookmark for google maps that works is to first create a bookmark for any other webpage besides google maps. Then edit that bookmark, changing both the name and the location. The location is the link that Google maps provide for the route you created.
