Nintendo's explanation is that they'd prefer it if people just focused on having fun with Brawl's online mode, not encouraging people to get over-competitive and kill the atmosphere for less-hardcore Smashers.
If it's that important to you, I'd suggest you rethink your priorities...tracking your stats would have been nice, but it's still a kickass game without it. And your stats do get tracked with friend matches I think.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
