Comment (by teor):
We should try to add enough noise to hide a single client's activity over
24 hours.
How many padding cells do you expect for a single idle client per day?
A recent measurement showed that ~20% of all entry connections are
inactive, so we should try to hide at least an idle client's worth of
activity:
We found that Tor has about 700 thousand unique clients
connecting to the network during an average 10-minute in-
terval. Compared to Tor’s own estimate of about 1.75 million
clients per day in May 2016 [4], this suggests that the client
population turns over about 2.5 times a day. Somewhat sur-
prisingly, we found that about 130 thousand clients have in-
active circuits during an average 10 minutes
