The rule is made to make sure that the Booker is worthy of being in the Power 10. If you have 10 posts and are put infront of a BTB that has 60 posts it doesn't seem fair. The 60 post BTB have tried really hard but a newbie gets in first try. But now that a lot of people are starting up their BTBs up again and doing well, they'll be a Power 10 in no time. And I am closing the Voting in 10 Hours.
