I'm thinking that it might just be easier on you if you forget about the percentages. They do however need to be grouped even if they don't like it. You should also know by now exactly how to recover with all the characters because of all the flaming XD. For the record, I'd like to see them do a better job, cause as far as AT vids are concerned, you did a way better job then any other AT vid out there.
So it'll be similar to the last one. No percentage, three groups, you probably don't need to do a recovery of every single opponent because it'll take up too much of your time, so even if you do a few of the more contraversial characters like Marth, and a few from each group so they get the idea. If they wanted to see every character, well you've already done it. As long as you re-do the ones that people weren't convinced about, then there's not much point doing the characters that everyone agreed on all over again. This way, it'll leave more time for the good stuff, like showing off the different ways to perform it and so on.
In the end though, it's your call and we'd be sweet with whatever you do.
As for taking over the thread, I see no need. The OP doesn't exactly need to be updated badly or anything, so don't worry about it. And I completely understand about not being so 'active'.
Anyway, I look forward to the updated vid. As always, take your time, there's no rush.
