Help reading a data log

96 Cobra with Perf tune from Bama.
It looks like it's running rich if I am reading this correctly (very high voltage on the read o2 sensors).
Also the bank 1 and 2 are not exactly the same at time +/-10%, but I am not sure if it's a problem.

Can't view your Y axis numbers for some reason but the two lines don't always have the same origins which leads people to believe there is a large difference between the two. You may be misreading, I know I've been guilty of that.

Also why didn't you run it to redline? Would have produced more information.

Thanks for having a look.
Yeah I know that they don't always have the same point of origin which is quite confusing actually, but looking at the numbers the difference between bank 1 and 2 rear o2 sensors can be 0.6 on Bank 1 while bank 2 is 0.2; also they quite often both go quite high around 0.8-0.9 (it should be around 0.5, right?).

I didn't redline it because I wanted to datalog with the way I normally drive to work, but maybe that was a mistake? (also, honestly, I never redline'd it, like...ever).
