I love general comments at the beginning of a peer-review Well, I don't know if all routes are really signed. I've wondered about Lv52 which is not indicated on OSM or GM. I couldn't find any 52 sign on GSV. However, it's indicated on
http://www.kortal.fo/ which is your source
I've checked Lv65 next. It's Lv69 on OSM but Lv65 on GSV and kortal.fo...
I guess you've strictly gone with kortal.fo. I haven't checked other routes for signs.
Comments to the routes itself:
Lv50:Shaping point south of Lv11
Rest is fine
