Good point Ben. For example, if the RC wanted to delay the onset of a new scoring system from 2011 to 2012 then the approval process gives them the ability to do so.
I was thinking more along the lines of, if the format is changed outside of Franchise GM, the current FGM RC may not want to adopt those changes. The FGM RC has approved the format in its current form, but has made no vote to adopt a format specified by a board-wide Scoring Committee, independent of this league, and any changes it may undergo.
