Without understanding this fully: thank you.

What is not clear to me: the function returns Mbps/100.
Why not simply kilobit/second?

Also: does it return expected_goodput or "only" throughput?
Because we want to use this value not internally only it should
reflect the real usecase (and should also be human-readable).

For a meshnet it is important to know, that a 10mbit ethernet line
is faster than a 60 mbit wireless link with a low tx-probability.
