They once released the schedules in batches of two or three runs. It was also much easier to backdoor your schedule early. They did however put out over and over again that schedules were never final until posted in DBMS. Despite the above they were inundated with phone calls and slammed on forums when a category was rerun and schedules changed prior to posting in DBMS. Seemed often to be someone claiming they ran out and spent 10 grand on a vacation they can’t change. They got tired of it. Frankly I am surprised they don’t just wait until 6 PM on the 17th to post them all.
