I was just wondering because of question #27 on the Application for
Certification of a road course which wants to know the type of surface (give %) and than it says if your course includes any unpaved sections, please attach a detail of the method(s) used to measure such sections. I am wondering if anyone has laid out a calibration course on the trail or in this part of the country we call it the towpath and the road and seen what the difference is? I may have to try it this summer if know one has done it.
