Comment (by karsten):

 From #33076 (mikeperry's words):

 > For #33077, I think it would be helpful to group the votes in some way
 based on which dirauths are using sbws vs torflow. Not sure if that means
 overlay all the CDFs or just combine them, or do some additional work to
 take the median values of measured and min_rate_observed from each set and
 make one graph for TorFlow and one for sbws votes. On the one hand, we
 will want to pick an option that is likely to be useful for future
 experiments. On the other, we will need to really dig into what the
 network load balancing would look like under each system.

 It took me way too long to match directory authority nicknames to the
 bandwidth authority software they were running around the time of Rob's
 experiment. It's not particularly hard, but I ran into several metrics-lib
 defects that I'll still have to fix properly. I finally came up with the
 newly attached graph that has one CDF per bandwidth authority, colored red
 for torflow and blue for sbws.

 [[Image(cdf-relay-stream-capacity-votes-2020-02-06.png,​ 700px)]]

 Is this graph useful? Any suggestions how to plot these 15 lines in a way
 that is even more useful?

 Unless I hear otherwise, I'll make two more graphs tomorrow for the time
 when the first authority switched from torflow to sbws (+/- 5 days) and
 another one when the second authority switched.
