Would this not extend lower-tier corps scoring lower until lineups are altered based on certain placements at regional shows? A non-Finalist corps will go on earlier, which impacts their rehearsal time since every corps only gets 24 hours per day.
If every corps starts rehearsing at 8 am but the previous season's 17th place corps has to eat by 4 pm to hit the starting line by 6 pm, while the last corps takes the field at 9:30, #17 will have far fewer rehearsal hours every show day. It seems like a corps has to come out smoking in the first week to make an impression on the judges, who it seems hold back numbers until later in the line-up.
