Consensus Health: what is the distribution of a bandwidth authority's measurements?
Once we know how many relays a bandwidth authority controls (legacy/trac#21992 (moved)), we might want to know how much it can change their figures, or how their measurements are distributed.
I'm not sure if we would use this, but I am writing it down so others can decide if they want it, and which option they want.
This option doesn't tell us the exact range for each relay, but it's easy to calculate and understand.
For each bandwidth authority, and for the measured bandwidth medians:
- the quartiles of its bandwidth measurements
This could look like: https://consensus-health.torproject.org/#downloadstats
This option is more specific, but might be harder to understand and use.
For each bandwidth authority:
- the median of the measurements it controls (the relays for which it is the median)
- the median of the next highest measurement where it is the next highest measurement
- the median of the next lowest measurement where it is the next lowest measurement
We should probably use medians for the average, because we really don't care about extremes.
Maybe this could look something like:
Bandwidth Authority Variance
Or maybe it would be better to express them as percentages of the median.
