Yes to either, that is what you say is correct but don't do both at the same time.

Adjusting the VVE is one of those things that you need to practice to get good at. You will not make one or two passes and have the VVE perfect, it just doesn't work that way. You need to make initial large adjustments and then reduce the values of the adjustments as the fuelling starts to become correct. You also need to learn how the adjustments will affect other cells when the VVE coefficients are generated. It just takes practice.
