Yep. It's basically the same complaint that comes out every contest/event where someone else, by virtue of their timezone and/or play schedule, can get more than others.
It doesn't matter that it's a 24 hr event and meant to give everyone at least one chance to hit it. If there's someone who can get more, other someones are going to get royally bent out of shape.
But I do think if they (per blue) are going to expand the pool of people that get to take advantage of that extra chance by giving advance notice they should do it right and give 24 hrs.
