I don't know what the accepted definitions of Adv and DS are. Both roads would be easily doable by me on my KLR and by the guys I ride with on KTM 990s. I don't know about GS1200 class machines, but I suspect they would be okay for any reasonably competent rider. There might be a fall or two in the sand on the Caineville wash road.
I looked at your tracks again and think I found the ones you mentioned. The names aren't exactly the same, e.g. Gap-Page is AZ 10-3 Gap-Page. They were all dated Oct 2011 though. I can't see how this could happen with the unit getting time from the GPS signal.
Maybe I need to go back and reload them from GPSX. But the track list is different from the version I downloaded in June.
