It's a number that I thought should be in about the right ballpark. The point wasn't to be on the mark, it was to be explicit enough about the estimate that would be easy for somebody to correct me if it was wrong. Which, it turns out, I was: looking around some more, it's closer to 1c per impression. That said, it's still easily in the ballpark of what would be a net positive.

Curious how you accurately got that figure knowing how draconic Germans are on protecting their privacy, I highly doubt they're cool with knowing that as doctors they're being tracked for some app targeting.

But yeah, anecdotally, just from visiting their practices, I also noticed most doctors in Austria tend to be in the Apple ecosystem for private use, but their practices and the clinics tend to be Windows.
