I am working on my timing tables but there is not a lot of info on how to tune for timing.

I basically started with a stock 454 timing table, added 4 degrees to the whole thing, then drive it looking for any knock retard. I take my history table for knock retard, remove the amount of knock retard from my main timing tables, and repeat the process.

Is this the correct way of tuning timing tables? Is there a better way?
