Scanner newbie with O2 sensor #'s, help please...

Ok I'm a newbie with OBD scanners but want to throw a few numbers out to see what they mean. I did about 15 miles 70mph live data, not flat so shifting in and out of OD. This is a 4.7 HO 226k miles WITH pre-cats. For O2 sensors both banks were consistent. Sensors 1 spent 70% of the time between 0.700-0.800, though would bounce as low as 0.80, 0.120, 0.220, but again, mostly 0.700-0.800. Sensors 2 stayed fairly consistent at 0.500-0.540. Same reads both banks. Any thoughts are welcome as I venture into scanner reading. So I'm not sure what should be happening here, if these are normal numbers or if either sensors or pre-cats are showing problems. Thanks in advance for all help offered.

Ok,,,,, anyone? I'm attempting to learn what these numbers mean from those who've been there before? 105 views so far.... Are my numbers gibberish? Curious please, thanks!

It smells good but thats about it
