Just FYI, I'm still testing two new approaches. I'll see which one deserves a further study.
So far V2 provided unreliable, but not completely useless. I'll see if I can integrate it as a double-check scenario

I'm also testing V3 which uses a different method, also independent of API

If any of these provide promising, I'll send you an invite. Sorry I'm keeping address secret for now (/v2/ points to old code), but as you can see I'm testing several options.
