What should I do about my main spark table?

[Mr Weston]

Usually spark changes of 1 or 2 degrees will change the knock retard averages. It can be challenging to reduce knock retard, because increasing or decreasing Spark Advance will affect knock retard averages. Sometimes adding Spark Advance will eliminate knock retard averages, which seems counter-intuitive.

Pardon for butting in, but I've just started playing with tuning LS1, and spark seems harder to tune than fuel, at the moment.
Dave W, would it be fair to say that having the tune take timing out due to knock detect costs you more performance than not having quite enough advance and no knock in the first place?
I base that on observation from logging. I have a 'test dyno' bit of road that I log acceleration from 2 to 5 000 rpm in 3rd gear on, and use time scale to measure performance, quicker the better.
Obviously no correction for airtemp, barometric etc, but pretty indicative, and 'real world' conditions.
I am assuming more advance is more power, but upon reflection of that, maybe that's not true.
And am I placing too much faith in my test method, as well?
Again, sorry for jumping in, not wanting to hijack your post rang-a-stang.
