Hi Maimun, this is a fine question. Actually, what you find on metrics.torproject.org *is* the estimated average number of Tor users per day, not the total number. Here's how we calculate those numbers (simplified): we sum up daily requests by Tor clients to the Tor directories to fetch the network status document, assume that an average user makes 10 such requests per day (some make just 1 or 2, others 15 or 20), divide the number of requests by 10, and have our estimated average daily user number. But we don't have data to say whether two requests were made by the same client or two different clients, mostly because clients can send their requests to hundreds of directories which cannot exchange data on requesting clients for obvious privacy reasons. That's why we cannot calculate total users per day, just averages. For more details, see these reports: https://research.torproject.org/techreports/counting-daily-bridge-users-2012-10-24.pdf https://research.torproject.org/techreports/countingusers-2010-11-30.pdf I wonder, why did you think metrics.torproject.org shows total users per day, and how can we make it clearer that these are in fact daily averages?
