Default Help Me Understand Timing

With the help of Dad (Brent) a couple of weeks ago, he helped me to put together the general pieces of the tuning puzzle for any car. I was very appreciative of this.

After running some more logs on a revised tune, my car is still pulling up to 3 degrees of timing from the knock sensors, ending up around 21-22° of final timing. The AFRs seem to be staying relatively spot on, however.

I know that air temp, fuel octane, and other factors influence the car pulling timing to protect itself, I just don't know the details on why/how.

I'm looking for help to further expend my understanding of this stuff, and to know whether I am still okay running my car hard in the colder weather now that it's hear, and that nothing will happen.
