Apparently I went from Germany to UK in 29 minutes, pretty good.

It's a 99.5% declared confidence and says it used 30+ signals.

Assuming you've a list of VPN IP addresses, and travel times between countries, I reckon you should be able to rule out some false positives.

Would be interested to know what the "signals" were that produced the match.

I'm on domestic broadband in the UK (IPv4), according to dnschecker they're on a mainstream mobile provider in Germany. Could be a private tunnel, but those would be rare. Which raises the question of how the confidence rating is made.

I like the general page presentation, a good landing page except that you'll tend to put off everyone who gets a bad result for the example. That might be turned around with something showing "if this isn't you, well done on your browser security" and maybe some compelling stats on confirmed matches from testing?
