To be honest i'm not sure how the two correspond to each other, but I do know that if you run out of trim (34) you risk leaning out. AFRs look very stable in my log so that doesn't appear to be an issue here. And the LPFP appears to be struggling...but that's what I want to see what others have to say!
Edit: Column S in your log is the LPFP requested PSI - 72, Column T is the actual PSI, which in your log is <72 most of the time. So yes your LPFP is not hitting the target PSI which is not good.

Hmmmm I need to do another log now and see how the fuel pumps in mine are doing...
