How would you find the optimal way to win one of these survivor contests?

Let's say you have 5 entries in a contest where you have to pick a team ATS per day. If your team loses ATS, you lost that entry. There is only one winner...the person who has an entry left at the end. You can pick the same team for all 5 entries or you can pick 5 different teams or any combination.

What is the best way to win this contest. My logic says to keep putting your most +EV team on all 5 entries until near the end when there are less people remaining. How can you quantify this?
