rating supplement tab on MSA update?

No big deal, but just wondering. Why does the rating supplement tab on MSA update so rarely? It usually seems that it takes about two supplements to pass before it will update to a previous supplements data.

The rating supplement records are loaded to MSA when the supplement is sent to the printer, which should be in about a week for the April Supplement. (That assumes that the publications department tells me when the supplement is sent to the printer, last time they didn’t so the records weren’t loaded until someone reminded me of it.)

You will only have a new supplement record when you have played in an event rated for that supplement or (under the new ratings system) if your rating changes because an earlier event was rerated.
