I mostly lurk (fairly infrequently) on here, but just wanted to post to say thanks for the Sqadrats tip. It's taken it a few days to import all my Strava activities, but now it's done it's great. I've long used Ride With GPS and the Squadrats Chrome plugin that works with that is fantastic. I also really like the Sqadratinhos which will make my (whispers quietly) running more interesting, trying to fill the gaps in my grid locally.
I've only noticed one tile that VV gives me but Sqadrats doesn't, but to be fair I think the road that I've used many times doesn't actually pass through the tile, and it's only GPS wander that's caused VV to credit me with the tile, so I'll revisit that and take a road that definitely passes through.
