Windows 7 Anyone else notice the Bitlocker vulnerability?

I think I found a flaw in the way Bitlocker handles manually entering your key that would make it very vulnerable to a brute force attack. You can read about it Link Removed due to 404 Error on my site.
It seems like I am the only one who thinks this a big deal. Is there something I am missing? Is my reasoning flawed somehow?

Turns out I was mistaken that the program was checking that each six digit key was correct before moving on to the next. The program only checks to see if the group is potentially valid by checking if it is divisible by 11.
This link Link Removed explains it well.
While it doesn't weaken the key nearly as much as first thought I am in disagreement with the site that " the work required for the attacker is not diminished" at all by these hints.
