When I check the route sheet to RWGPS, the first 3 controls are significantly different to each other. From control 4 onward it converges. EG Control 1 on the Route plan says 258k but on RWGPS its only 216k.....What have I misunderstood ?
The start has moved by about 40km west. I suspect the route sheet is in error.
If you're referring to the official, two-page routesheet or route plan from ACP then likely they haven't updated it since the move to Rambouillet, 40km west of the original St Quentin start.
If you're referring to my unofficial, 12-page routesheet then I deny all responsibility ...
The official route sheet in the dossier says 144km to Mortagne au Perche. I think that's way too long given the moved start, and the open runner route on their website has it at 117km.
Edit: what I'm seeing is actually a formatting error in the route sheet. The control distances are correct, but are not lined up with the instructions. This seems to only happen for the first column, so it's incorrect until Quedillac when I look. The issue varies between my Mac in Pages and Google Drive; I don't have Word here to compare.
However, the controls are highlighted in bold in the distances. So they are Mortagne 118km Villaines 217km, Fougeres 306km, etc.
This lines up with the RWGPS distances you quote (give or take the odd km). So both are correct, as far as I can see.
