I've never bought points, nor will i ever do so in my entire life ...,
So as an acolyte my only epifany is that with calculations in cpm/cpp valuations.
Everyone seems to forget that Hilton, Marriott, Hyatt allow redemption for most room types:
standard, superior, deluxe, executive/club & jr. suites, premium suites.
While at IHG we are stuck with redemption for standard rooms ....
or even worse *shudder* the infamous ......cosy/cozy !
Which surely must impact the valuation of cpm/cpp.
