Lol, Chaazziiee (Charelle) is my younger sister, she takes what she knows from me and my brother over the years (big mario kart fans) but yeh, she got a bit lucky in some of her matches but on average she was only doing one miniturbo a corner, for some reason a lot of the racers in her races last night just kept driving without miniturbos, and due to only being 4-8 player races (continental) not many blue shells.
You got some bad placings in the matches she was in i gotta admit man, usually coming in the back half of the placings, while her, vez and becky were usually racing for top 3 status.
I can nearly lap her in the majority of the DS tracks, and still fairly dominate her in the Wii tracks, but its all about miniturbos, taking the right line, and defense for the most part, and of course, knowing the tracks, i've finished the single player already, and multi have a 180-28 win/loss record, while shes only done up to 100cc and with a 38-37 win loss record (in some of the matches you weren't in, she finished 6th, 7th, 8th). Maybe she just liked owning you last night rofl
(Actually, she was really only focused on Becky lmfao, but we were surprised at the bad luck you had in her races, as a few times she came first, she'd fallen off the track 4-5 times, and still no one beat her)
Was your brother one of the guests in those games last night, there was usually two guests per match floating around.
