@Martin-van-der-Linden Wow, you mentioning Offroad is a game changer!
The algorithm tries to match your track with the roads that exist in the map used, that's how navigation on a map works...
Offroad is a very special aspect of the routeplanning, and I'm not sure if this type of routes/riding can be designed correctly in the maps available in MRA. Note that Offroad requires waypoints to be set to Offroad/Skip to correctly be an off-road waypoint.
Perhaps one of the more experienced riders and MRA specialists will respond here. @Hans-van-de-Ven-MRA-Master or perhaps @Nick-Carthew? These came up in my head straight away, definitely not saying others are not as experienced.
