PKNintendo, this is a pretty interesting list, and, overall, I find it to be generally accurate, but the most glaring flaw, in my opinion, is that Marth is much better than Mario at recovery, since their up-b's are basically the same, but Marth's is faster and goes farther. Also, Marth has better aerials and he can side-b after his second jump to gain height, and use neutral b to gain tremendous distance when recovering from the side. Another problem with this is Wario, sure he has good aerial movement, and his bike jump is good, but his up-b is absolutely terrible, and if the Wario has left his bike on stage, then he's pretty much doomed. He should still be high, but just not that high. Also, Pit should be higher because a good Pit generally won't even use his up-b. Pit can also fire arrows at any edge-guarders, and he has a very good glide and glide attack. Finally, the last problems I can see are that Ness should be higher than both DK and Peach, because of his amazing second jump and aerials (especially fair), even if his up-b is gimpable, at least he can make it back from spikes, such as Falco's chaingrab>spike.
Also, this may be a little biased, since I main Falco, but he should be higher than both DK and Peach, because he can match either of them with horizontal recovery (Phantasm can be cancelled at 3/4 to give extremely fast and long glide) and he has a longer distance up-b.
Thank you for taking this into consideration.
