Replying here rather than on
https://trac.torproject.org/projects/tor/ticket/1819 , since this is
where the discussion of the "bidirectional connection counting"
feature started. I'm hoping that Björn and Florien (or somebody who
knows their work) will point me at some kind of writeup to explain the
motivation here. Why is the fraction of "bidirectional" connections
important? What does knowing it get us?
many thanks,
