I think the situation imagined is in a building with good wifi
access, but crummy phone service. I hadn't thought that wifi
would be that much more accurate than the cell tower location.
I hadn't imagined a lookup table with 50m resolution for every
wifi router in existence, I thought it was going to be more like
the "location targeted" banner adds that pulled your location
from your ISP. I could also see the wifi location being updated
if you ever connect through it and have gps active, but prior to
that I'd expect a big accuracy variance.
