Hiroshi brings up an interesting topic. How often will the official list be revised?
I, for one, believe that revisions should not be made after every-single decent sized tournament. It's unnecessary to revise the list that often, as it would likely not change drastically, or even at all. The list should be based over an extended period of play (like it is now), not 1 or 2 months. I wouldn't favor a revision after SUPS.
The panel could possibly designate the list to be revised quarterly, or maybe semi-annually? Another approach could be a revision after (X) major tournaments that are at least (Y) months apart.
