I believe there is an error in task description:
" The second session contains two requests (4, 7) " should be " The second session contains two requests (4, 6) ", and " And the last session is the request (6) from "user2" at checkio.org." should be replaced with " And the last session is the request (7) from "user2" at checkio.org." ?
