They are clearly different paths of award progression now. RCA and DCA candidates both get to iterate their submissions now, but DCCA is still a one-shot thing (for multiple slots) like Regionals used to be. However, if our currently sparse Michigan numbers are any indication (which I am not saying they are, but it's all I have to go on) some Districts have very sparse fields of submissions (2/26 and 4/30

).
The idea behind collecting these stats was mainly to see how the new multiple-submission rules affected the RCA/DCA wins.
