I think the Tour made a smart move with the scheduled conclusion to the FedEx playoffs scheduled to end prior to the start of football season. Now there are only 2 elimination rounds and then the finalists move to East Lake.
Also, the final weekend is handicapped based on the where the final 30 players stand in rankings. In a nutshell, in theory, every player top to bottom has a chance to win it all. If nothing else, fans at home (and the players themselves) will know where everyone stands 'at a glance' instead of having someone going through a slew of 'what if' scenarios on a whiteboard to project the winner under the old format.
