Thanks for posting the numbers you found in that other post!

I meant to respond to this post, but I wanted to write some code and
include some numbers myself, but then I got distracted by something
else.  Anyway.

Regarding your suggestion to add this as new graph to Metrics, I'm
afraid that this is an even bigger coding project than adding something
to Onionoo.  We'd have to write a data-processing module similar to the
recently added webstats module, plus some graphing code.  We don't have
the resources to do this, and while I'd love to make this process
simpler in the future, we're simply not there yet.

However, I was wondering whether we could use this analysis for one of
the metrics-lib tutorials that we promised to write for our Sponsor X:

    2.3. Write user-friendly tutorials for metrics-lib/DescripTor that
empower users to independently analyze large amounts of network data.

Can you share the code you used to come up with those numbers (20.6% of
exit_probability has EntryStats enabled)?  It's okay if it doesn't use
metrics-lib.

And what other numbers would you want to know about statistics enabled
by relays?

All the best,
Karsten
