Depends on what you're doing though I guess. I change the base table to adjust anything on low-mid load to remove knock. In the high load areas, I have a flat table of (for example) 6 degrees. Now if I prove I have no knock, I up that by a flat figure, say 0.7 degrees. If I get knock after that, I can reduce where necessary in the advance table but I can continue to add timing in other areas. It's clear as day the next time I do the same where I should not add any more timing and where I can. This would not be the case on the base table, unless you have a very good memory or note it down. In my eyes, adjusting the advance table is the easy solution. Once you get to the stage where you are happy, you can always adjust the base table and flatten the advance table again, or have it how you like.
