Huh? How is that not exactly the right answer? You tell the API how accurate you need it to be, iOS will get you that accuracy with the minimum energy consumption necessary.
It makes sense to not document the thresholds because they probably aren’t constants. (Or even if they are, they might not be in iOS 14.) It’s entirely possible that the accuracy of non-GPS methods may improve over time.
And they would certainly vary greatly depending on the environment. Who knows, if you’re in a concrete jungle with very dense wifi coverage, it could even be more accurate than GPS.
Conversely if you’re in a tiny rural town with one cell tower and no wifi, it might have to turn on GPS even if you only need 50 meter accuracy.
