To elaborate on my earlier comments, my proposed entry plan
can be found here
Pit entry would occur at the Washington entrance, well away from the Dome. This would be allowed before doors open (1.5-2 hrs early, ideally) and team members would queue outside the pit entry doors in the blue oval. This separates a large portion of people away from the dome entries, substantially reducing issues off the bat.
Dome entry would ideally occur through Entry A, B, C, and D, but I can see how manpower would be a problem for that.
Alternatively Entry A can continue to be used, along with Entry C. Team ideally are also let into the second level of the dome 1.5-2 hours early to queue in the green ovals on the level 2 diagram in the concourse outside of their division.
If its not possible to let teams into the dome early, at the bare minimum if entry C is employed there should be 50% as many, or fewer, teams in line at entry point A as there were last year. Probably more like 1/3 as many, as I imagine roughly 1/3 want to go to the pits immediately. Combine this with some crowd barriers and effective crowd control and problems should be nearly eliminated.
