When dialing in the maf and multiplying by the % error should I only be changing the 600+ hz. columns?

I know the timing map should be a gradual increase instead of a rapid vamp on numbers but the numbers in the middle how are they derived or what are they calculated from? As to my understanding the higher timing in the middle creates higher cylinder pressure and then that's what gives you the great MPG.

Partial throttle tuning the LSJ can someone possibly lay it out or point me towards some litterature that is beneficial.
