Correct me if my thinking is off, but generally speaking shouldn't it be easier for EP's to handle crossovers if teams are following the summit crossover rule? If they anticipate crossovers will only be one level up or down from another than strategically placing adjacent levels in halls next to each other would help minimize most people from having to run from hall A to E. The 4.2's would still possibly have to run since they can cross to levels 2, 3, or 4 and there may be an odd team that doesn't work for or that doesn't follow the summit crossover rule, but it seems like it would be somewhat easier to schedule knowing as many Susie's aren't going to be crossing from 4 to 2 anymore.
