I figured out how they (Great Blue North) are getting their numbers. They are using the entire season -- all 16 teams on the schedule using the current records -- whereas the draft order you've calculated is focusing on the games that have been played and will calculate future games as they come. Their calculation sees 101 wins divided by 192 games = 0.526 In their calculation, each week a team's wins goes up by 16 or less, and the number of games goes up by 16. Pretty small fluctuation. Their draft order could end up being closer to what it will look like at the end of the season.
