The only reference that that I could find quickly googling, is the repost of repost of repost of some unspecified study that someone did, measuring readings from some unspecified fitness bracelet. Even if we assume it exists, even if we assume it measures correctly, even if we assume it’s not an ad for something, it is a study about people health conscious enough to buy and regularly wear a fitness bracelet. And among this cohort, the average is just 3.2 km.
I agree, it’s a bit more that 300 meters, but not by much actually.
Sending a temp updates to your phone so you don’t have to be standing near it the whole time is a nice feature.
