It is important that the rating's impacts are supplied at the end of month so the next month will use the latest player ratings as the starting point. We have made a decision to process on the first day of the next month irrespective of whether the impacts of all clubs are available or not.
It is important to realize that you do not need the events from all the days of the month in any month's run. It is better for you to process the month-end a day or two early than to miss the month-end run. Therefore if you think you will be unable to do it on the last day of the month then do it a day or two early, at your convenience.
