Or to explain it another way, if you fix the flow + yield/ratio to balance bitterness/sourness, you've got a contour on the dose/grind axes to move along (as in your example, 15g/fine to 17g/coarse are both on that contour, as is presumably 16g/medium) and the position on that contour determines the "boldness" of the shot.
What I've learned from this is that all my shots are shite
