Yes! That's what I think I'm seeing also. I think FRA & FRA2 are supposed to be 1 and are both 0.97, TRA and TRA2 which I think is STFT? are both pretty much zero,. The only one that appears to be slightly questionable is O2 ahead of cat bank 2 which should be 0.5. and is 0.73. What I think I'm seeing is that these are pretty much what they are supposed to be, however It appears the MAF is introducing some fluctuation and possibly needs replacing?
One thing I need to verify is what is STFT and LTFT? The durametric does not define fuel trim that way.
