The setup posted in Discord is : 2-0-0-3 for where to put your squads (left to right). Don't use girls that have the 'ignore spiderwebs/whirlwind' ability because that will mess you up.
That setup with 5 squads that are almost all between 520-560 in speed (one just over 600) worked for me the first time, and a couple of subsequent runs as well (not that there's a benefit after the first run).
