STFT Question - Logs Attached

Hey,

I just changed out my lpfp as I was dipping below 50 in higher rpms. Everything looks good now except my stft are fairly eratic and above 5 apart. They were this way before and after an adaptation resets.

I've tried reading around but still don't understand if they are within reasonable spec. The idle looks good which means my injectors are alright? But, since they become farther apart at higher rpm it could be o2 sensor?

My afr looks good and the car runs well so maybe I shouldn't be concerned?

Thanks!
