ha. what I've learned from reading the comments is that it's not necessarily necessary to compensate for this error. (I also guessed 400 as a lower bound.)

  Most likely everyone commenting was compensating for error, as the author primes you by telling you about the error before asking you to guess. If he had written that people tend to grossly overestimate, I bet you'd have a very different result.
