Here is another potential strategy. DCC at its core is different than all other events, because "action" is encouraged. There is an action room available 24 hrs per day, and the main tournament tables are open after the matches conclude each night.
Some of the suggestions have been to minimize the action tables, and allot them to the main tournament. Other comments have suggested the pros don't even gamble much anymore. Other comments have been the times are different now than 25 years ago when action was more prevalent.
With the schedule the way it is now, if a pro wanted action, they actually could not do it. There is simply no time. Wheres when the fields were 200 players per division, and there was no Fatboy/Bigfoot, there was plenty of time, and much action was had.
So, even if all the tables were utilized perfectly for the tournament, 500 player fields would still prevent the pros from engaging in action. If the fields were limited much less, to let's say 300 max, then there would be a shift, and the action would probably return, due to extra free time.
With all that said, a direction may need to be chosen for the DCC. Is it more action? Is it more tournament? What is the split? The answer to that could lead to which of the solutions to scheduling to implement.
