Matching weight, swingweight, balance and sweetspot requires adding weight at three different locations.

The "Swingweight" heading only appears when Customizer can't match all four of these specs.

When that's not possible, Customizer will try to first match weight and swingweight. Failing that, it will match weight and balance.

Matching either of these combinations only requires lead weight to be added at two locations (shown in columns 2-5).

The resulting two unmatached specs (either balance and sweetspot in the first scenerio, or swingweight and sweetspot in the second) are now shown in the 5th and 6th columns. They vary with each solution.

You can choose the solution with the closest of value to your desired specs.
