This makes more sense to me if rather than a linear mean we think of multidimensional means.
If we put this notion into the physical world and imagine your values as part of a physical object - then your central purpose could be that which is in the center of your values. From a physical perspective the central purpose can balance your values. However - for physical objects the center of mass may not be part of the object (think of a ring - its center is in the middle where there is no actual mass - you cannot balance a ring on its center of mass unless what you are balancing it on is larger than the ring).
...I like the idea. Not identical but reminded me of a saying that you can't cross a 20 foot chasm with 2X10 foot jumps.
Disatisficing?
You also included an existing term in your post, “half-assing.” You won’t get sh*t done half-assing.
