It certainly is confusing! Pulling a plug and giving it the ol' sniff-test might not be so bad after all.
And if you are like me.... you won't actually believe what the gauge tells you 100% and you'll be pulling the plugs anyway. LOL
I have a wideband integrated into my Megasquirt MS3X system - which allows me to datalog every single part of the operation during a pass. I was running an AEM gauge connected to my system - but the Bosch sensors didn't survive more than a couple of passes if I put it up on the 2-step launch limiter. I switched to an Innovate system and so far so good. The O2 sensor has lasted a year already, so that's good news for me!
