• The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
• The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

It seems that it is consensus that this is good (#36911 was merged). Could you add this PR in the issue?

Can you also do a follow-up PR for semilinearMap?

Thanks for the fast review! This PR is already referenced in the tracking issue #31365 --- that's what you meant, right?
Let me create a follow-up about semilinear maps next.

[grunweg]

(By the way: #43367 does the analogous rename in a few more cases, and is also waiting for review.)

[mcdoll]

I meant as in putting it in a list in the issue under point (2), similar to the list for point (4).

[grunweg]

Ah! Good idea; I started a list.
