I don't have hard information here, but I suspect the number is far lower. Each one of these requests is likely for a very small time period; keeping a single individual under surveillance likely takes a large number of requests. Furthermore, the vast majority of these requests are subpoenas (161K) which can be issued in divorce proceedings or legal tussles over car accidents (was the driver texting?) among other uses.
