First chart: Agree with the above conclusions that the 1st one is too lean and the advance multiplier is too low. The ecu is not happy with the calibration. Caveat: the multiplier is on its way up during your data logging, so potentially that 0.46 could go back closer to what it should be.
Second chart: This is better although I would ask the tuner to look into those knock corrections. They don't happen under lots of load so I am thinking it may actually be just phantom knock or tip-in knock like someone said. As for the advance multiplier being at 1.0 how long was this car driven with this particular ROM. If it has been driven for a few days and the multiplier is at 1.0 then chances are the ecu is happy with the calibration.
