I think position sensitivity may depend on the equipment and the engine configuration.
I have my AFR O2 sensor located in the stock J-pipe Lambda location, before the turbo, and it has worked flawlessly for years. I check and tune using the bung right after the turbo and see similar numbers. The response when the throttle is lifted is different as you might expect. The dyno shop that I use runs the typical tube up the tailpipe and gets consistant readings above idle.
