Competition with the War and Peace

My former student Brad Fl. wrote me two weeks ago a mail:
Hi Dr. Erdi,
I saw you wrote a new book “Ranking”… Congrats! I’m working on reading War and Peace right now but that’s next on my list 🙂.
Two weeks later I asked him about his progress…
“Slow but steady” and attached this pic. Any guess, when he will read Ranking?
