I only logged about 3 hours of data and tried to hit every cell I could but some were hard to hit.
I was also thinking of just going to Open Loop all the time.
What does everyone think?

You can definately do this, but I'm not sure what benifiet you would see. While you are in closed loop, the PCM is trimming the fuel based on O2 sensor feed back, so your WB reading will represent the AFR after trimming.

I would think you would get a better idea of what's going on by monitoring your LTFT's.
