OK, even though I started this thread, I'll take a stab at it...and for full disclosure, I have no idea what will really happen. That's why I started the thread.

In my experience (this will be my 4th festival), the Planet is usually pretty reliable with set times (i.e., if they say 10 a.m. is start time, Chris will probably start pretty close to 10) and the opening set is about 45 minutes. But, like oddfired suggested, it's probably best to avoid such specific speculation for the sake of the people who won't read very closely.
Yeah, they do run a tight ship!
However, my guess is that programs are going to print very shortly, if they haven't already ... which means the schedule will have been written in stone.
(Just curious if cheese will be allocated any more time vs. the standard 1:15)
