Yes, but the hard part is that none of it is a guarantee. So do I make sure none of my preferences conflict, to maximize chances of attending panels? Or do I book two or three at the same time, knowing that I might not get my first or second choice in that time slot, but I'll at least get one?
Then, there's my own meta-game, about wondering if their system takes into account choices across different days to try to ensure people get at least a few of their #1 choices? If so, if there's just one panel I really really want to be in (cough Marvel), then it would actually behoove me not to pick anything else in Hall D23 on a different day. But I'm not sure that's how their algorithm works. Yes, I'm overthinking it.
