I'll edit this as I go along these missions to refine the details and organization. Looks like this week's more about speed management than RNG, although ?-12 IS annoying the hell outta me.

?-7: 2 North, 3 South.
1st North Squad Fast, 2nd one slower

?-8: 2 North, 1 Center and 2 South
Fastest squad center, slowest squads, North

?-9: Standard Setup
Slowest squads up top, fastest going down

?-10: 1~2 North, 3~4 South
1st and Fastest up North, adjust according to speeds

?-11: Standard Setup
2 Fastest Squads up Northwest, 2 Slowest at Northcenter

?-12: 1 North, 1 Center and 3 West
Fastest Squad take North, Slowest takes Center and West for everyone else; that Locked Panel down south that's hiding a pest is the biggest problem here.
