Idle Tuning - In Park timing table

so at this point if we wanted to add more timing I wouldn't feel too comfortable guessing where to add it in the In Park table. We could willy nilly it and change all the cells that say 19 in the upper left hand corner and add 2 degrees to them making them all 21, but that would be stumbling in the dark, because all we know at this point is what RPM we are idling at but not where we land on the Y axis aka Cylinder Airmass, and we remember from our Timing discussion that GM likes to use RPM vs Cylinder Airmass to plot their timing curve.
