No experience of 4 sensor set-up but that would look fine to me.
There can only be one STFT per bank, and I believe on the 4 sensor set-up that Sensor 2 controls fueling so the numbers make sense.
You should see Sensor 1 voltage stable, and sensor 2 voltage fluctuating constantly - that's what controls STFT.

The reader may not decern between the different tintania base O2 sensors on the X300
Off the top of my head 3.5 volts DC return voltage from others
The target value on all engine ranges is 0. 0 % but + or - 3.0 % is best expected from real world expectations and reading from others
The end limit of the readers readings is around 24 % if off scale
Fuse Y to heat all 4 sensors to read correctly
Grounds and connectors clean ?
Connectors not swapped as common ?
See page X for the AJ16 engine

Highway milage OK as the other final measure of engine regulation final refinement / tuning ?
There is no manual tuning but .......................................
2 wire coolant temp sensor reading above 88 C to have the O2 sensors used in closed loop engine regulation ?
The aft 2 sensors are used for engine regulation , S2
