WER, GPTs and exactly 8 players
One more thing to consider, which I personally only very recently experienced, is that the DCI system will only accept tournaments with a minimum of three rounds. So, if your top 2 (or top 4 or even all eight) players choose to apply the DCI policy to prize split and drop from the event to allow a single player to “win” and get the bye, the event will be automatically invalidated. In my case, to meet the needs of both the system function and the rules as written, the results, if any, will have to be manually reported and the bye assigned by Wizards manually and the event invalidated. As far as I know, there is no policy regarding this anywhere and each such situation is handled case-by-case.
