Have a look at the graphs in the paper:

They were collected from tests on real hardware where I put in a
temperature probe. Some are from local connections and some
transatlantic, and in both cases the quality of the results were good.
Without that much analysis, differences of 1--2 C were detectable.

The source code is online, so you can also try it yourself. To get
accurate results, it does take quite a while. My tests where typically
8--12 hours:
