Bobby Wasabi and the Black Dragons agreed to use the Advancement Tournament to evaluate students desiring to prove they deserve updated belts

 * Bobby Wasabi and whoever owns the Black Dragons dojos must have felt it to be the best way to ensure the students who get advanced belts really deserve it.
 * Given how Rudy had initially tricked Jack into entering, is it hard to believe he'd simply give belts to two of his students if he thought that'd save the dojo and his job?
