At the risk of sounding like a basement dwelling lazy millennial, could someone with map skills stitch together all the Strava segments from each of the accounts we know are RYs, to visually present the missing stretches? Some places will have two or three traces - some from the legit data uploaded on the Joanna account direct from the TomTom - and some from the massaged GPX data from the Rob Young account and his other sandbox accounts. If they are overlaid on a map it's a visual way of showing what's been shared and what has been conveniently left out, and for which account. I just don't know where to start doing that kind of task.
