On Zynga's Shootout mode what is a good winrate to aim for?

Since it only counts first place as a win and ignores when you profit but don't get first place, what's the point of this mode? In Round 1, you actually lose chips even if you get 3rd or 2nd, it just means you lose less for those places and only first gets their chips back.

What's a realistic winrate for a winning tournament player to aim for in this mode?
