Could very well be just me, but as a 30-year+ amex platinum card holder who used to book almost exclusively through FHR, I have found the upgrade benefit to be getting notably stingier over the years. Especially recently.
Wonder if that's true universally.
(and i mean 'universally' two ways - first, whether other amex FHR/THC users feel that trend too, but also whether other similar programs have tightened up on their own upgrades)
