I have a single wire Bosch sensor in my Holden (Chev) engine and have made up a 0 - 1000 mV meter plus a Summit air/fuel guage to back it up. Both show wild fluctuations between 100 - 900 mV after only 2 - 3 miniutes.
At cruising speeds, no acceleration or deceleration I see around 400 - 500 mV.
The sensor is positioned just after the weld where the 4 header pipes join the collector. I believe the sensor is working ok.
