It seems to be more frequently when I'm tuning in SD lately that I get erratic timing showing up on the logs. I've tried at times to log just for this, but haven't found the real answer yet. Here are some random examples.

I have noticed this as well in the past.
have you zero'd out your burst knock tables, the change in airflow apparently confuses the PCM and causes timing like your seeing with SD tune. zero all the burst knock tables and see how you go, just make sure you listen for det on a couple of power runs.

I had this happen to me as well on my Camaro and I went through and double checked everything I could and stumbled across my dynamic airflow disable RPM being set to stock but running SD. I set that disable RPM from 4000 to 9000 and it fixed my problem.
So you may try doing that.
