I briefly looked at the raw data behind this graph, but didn't find any
obvious problems with the algorithm. I'm running out of time now, but I
can share some preliminary results in case you want to dig deeper:
is the graph that you posted with a third line for mean values.
contains numbers of responses (for requested consensuses) by bridge,
transport, and time interval.
shows responses by transport.
shows only <OR> and obfs3 responses over time.
shows only <OR> responses higher than 1000 by fingerprint.
is the bridge reporting those high numbers for <OR> responses. Is
PacificSunset maybe one of the bundled bridges?
That's all. Maybe it helps?
All the best,
