[tor-dev] Question about estimated number of clients

Dear Dr. Loesing,

If it is possible, can I know the peak number of the concurrent clients?
For example, you publish a single number per day, like 200,000 clients who
are simultaneously using Tor. This number without geographical information
may not hurt the anonymity, but it may help me know how popular Tor is and
how much load is on Tor.

Best,
Lei
