Addition/Substraction of the values is correct only when your initial flow is 1. Value of 0.02 on the printed thingy means 2% more than your current flow (0.96 * 1.02 = 0,9792). 0.98 is close enough I would say, I often just add/substract it like you but I wanted to clarify this anyways since that's a common misunderstanding.
There's per object flow setting in Orca. That's how builtin flow calibration works - spawns few objects and sets the per object flow there. You can even control the flow per bridges (internal/external) and top/bottom surfaces. Also there's small area flow compensation but in per object settings you can only enable/disable it - it cannot have different settings.
One more thing that I would like to add, the 3D printed cubes are too small in X/Y directions. Eliss's cubes are better in this regard since they let you focus more on the middle of the print where Pressure/Linear advace and acceleration does not have much influence on what you actually need to look for. The bigger the cube, the less chance that PA/LA/Accel biased the result. Eliss explained it a bit better than I: "Focus on THE CENTER of the test prints. It’s normal for them to look more overextruded near the edges and corners."

Thanks for the info. I missed this. I pinned your comment.
