Analyze how wrong our bridge usage statistics are
Our bridge usage statistics are based on the reports from bridges with at least 24 hours uptime. If bridges are shut down before that time, they won't tell us anything in order to protect their users' privacy.
We should find out what fraction of bridges have less than 24 hours continuous uptime to say how wrong our bridge usage statistics are.
See also Section 7 of our technical report for a more detailed description of the bridge usage statistics and their problems.
