Default Narrow Band: volts/AFR question.

I was reading a artical on TurboSaturn.net and it said:

At an air/fuel ratio of 14:1 the oxygen sensor voltage signal would read 1.0 volt on a narrow band sensor. If the air/fuel ratio mixture is rich than the sensor would read fewer volts or conversely if the mixture is lean the O2 sensor would read a larger voltage. If the air/fuel ratio is richer than 11.7:1 (0.8 volts) or leaner than 18:1 (1.22 volts) the engine won't run.

I allway's thought that with stock O2 sensor's, anything below .9 volts is lean and any thing above 1.v is rich, according to this artical I'm *** backwards??

What is the correct Volt/AFR?

Well, I know you guy's know the right answer. So does a stock narrow band 02 give a higher or lower voltage when rich?

i think the narrowband o2 can only read up to one volt or so, so anything after that in the gauge would read rich.

i might be wrong, so don't take my word on it.
