5 bottom is worst I think. You completely bypass left farm circle, and each squad has only 50% chance to turn down on RNG node and go to right farm circle.
Supposedly best one is to put all teams on top starting spot. Each squad has then 2 chances to move to right circle, so 75% chance. You also get more chests, and few passes over 4 trophies breads.
I tested also putting all teams on middle starting spot, but as long as you remove RNG of squads reaching farm rings, as that starting spot is directly connected with left circle. That circle has only 5 16-trophy burgers and 10 8-trophy rolls, whereas right circle has 10 16-trophy burgers and 4 8-trophy rolls - AKA left circle is worse to farm.
