I get about 200 or so passes on an NTK sensor using unleaded race fuel, sometimes more. This is with the Holley system. The Bosch sensor is about half that. If you limit your correction to +-5% or less, then if a sensor does go south, it won't kill the tune that bad. But, you do have to look at your datalogs and keep an eye on things....... I run Closed Loop in both of my cars, but also limit what I allow it to do.
