• 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).

What changed here?

[vihdzp]

I just made it private as it was supposed to be; all it took was adding by exact a few lines down. Note that ordConnected_preimage_mk is the public version of this declaration.

[YaelDillies]

Could you let know whoever removed this private?

[vihdzp]

I believe this was a largely automated task done by @jcommelin in #33034.
