My question is should I be combining the cl/ol corrections together? Also does this sound normal?

Yes sounds normal.
might be worth just applying the CL corrections, then check the OL again after that. Yes sometimes you have to average them.
The CL corrections should be somewhere around what your LTFT are the OL corrections will be the difference between the AFR measured and AFR commanded (in OL fuel tables).
Make sure you do the logs at similar temperatures, wide temp variations will cause problems. If you could do them around 20-25 C this is ideal as that is where their is no temp compensations applied not always possible though.
