If you go to the news updated section on the first page of pfc, click on the more news tab at the bottom, and then click on the flight operations update just above the final results of posting 09-03 you will see the original (as far as I can tell) update from the VP explaining the drop of an R day. It is undated so its tough to tell when it came out, although it must have been after 09-03 closed. It mentions details would be published later but I can't find an FCIF with any further details.
