 This closes the loop on #31435 to help us validate that the poorly
 performing relays have indeed been excluded as we would hope, and then we
 can check that we're not excluding so much performance that it would
 degrade the experience for everyone.

 This task does not depend on #31435 however and can be progressed
 independently.

 Some questions to answer:

 1) Low hanging fruit: are there some trends we should be aware of before
 we dive into this data, for example are there some "peak hours" where
 things are slower, or do things get slower on weekdays/weekends.
 2) How much data do we have to look at to identify with some certainty
 that a relay is slow? (1 day, 1 week, 1 month, 1 year?)
 3) What is our metric for "poorly performing"?
