Comment(by mikeperry):
Karsten: The votes for urras in these two graphs look odd to me, so I want
to just confirm I'm reading them right.
On the relay-votes graph, it looks like 60% of the Guard nodes have a
ratio of < 0.1 (I assume 0)? Similarly, 40-50% of the Exits also have a
ratio of ~0? That seems to be a lot of nodes with no capacity.. Yet
urras's measurements look fine when not in PID mode. Definitely a bug
somewhere, it seems..
On the measured-votes graph, it looks like urras hates Guards and Exits so
much that their total measured bandwidth is way way below what the
consensus has, and so their CDF only goes up to like 10-20% of the
consensus total? In other words, you did not scale these graphs (which is
fine). Is that also right?
