...whichever floats your boat.
But you used a word that was new to me: "orthogonal"
It set me off on an enjoyable exploration into it's use/meaning.
I got into it's various uses, but in computer programming, it lead

Applying the five Key Process Areas (KPA 1-5) to Oregon's experience with Vote-by-Mail,
it's clear our elimination of old school voting booths is now mature,
and meets Oregon's original [orthogonal] goals !
In any case, I think I learned a lot ... and no hub caps were stolen !
So, thank you
