Comment:
Karsten and I discussed this about a year ago, and came to the conclusion
that rounding to 10k cells was sufficient, especially since these counts
are accumulated over a full 24 hour period. Relays are already reporting
higher resolution for BW read and write history, and relays that opt in
have higher resolution for cell statistics too.
Is there a specific thing we're worried about with the current numbers?
Can we quantify the additional privacy we'd get from noise vs just making
the rounding larger? Should we do one, or the other, or both?
