Nice, congrats. So, seems like it's possible the whole shebang works without your real data, at least if you have a spare, non-ID'ed phone and are being very careful. I guess the yield comes from the unlucky masses who don't fit that pattern.

In any case, I'm not gonna try and outsmart them for a few thousand sats, but I also won't recommend against anyone willing to try. Stay safe, and good night.
