Did you read the link? Suggests McFarland, who may also be waiting for....doesn't matter. What does matter is (1) whether TCF's choice depends on space, (2) whether he's next in line for a specific open space pending another's decision, (3) whether another (perhaps previously allocated) space opens up due to an unexpected flip, etc., etc. But at this time of year, anyone who knows where he wants to go and has a committable offer has already secured his space, whether public, silent pending announcement, reserved pending, etc.. All the rest are subject to the numbers game...at whatever program is at issue...
But that doesn't mean we're not all as curious as you...
