Putting my second fastest squad in the far right tent and everyone else in the far left tent works for me every time.

Edit: I misspoke because I confused this with the 80 stamina map. I actually stuck my slowest (553) squad on the far right. Everyone else still goes left.

I stopped reading the stories after they put maintenance several hours early without notifying their players via the scrolling bar, missed a set of event equipment because of that
