Too individual an evaluation IMO for mathematical precision (a cat 4 at $200 is stretching these days), but curiously I also concluded it’s around $20.

Calculation has changed since COVID, but here are a couple things:

Free parking on awards/free nights in cities can be worth a ton to some people and zero to others.

Four weeks of suite upgrades likewise.

GOH reservations as well. “Loaning” your status to a boss could be worth a LOT. Or giving someone a week honeymoon in a fantastic suite somewhere.

And night 60 on Dec 30 is REALLY worth a lot.
