The policy is that cash upgrades (time-of-departure and at booking) do not earn additional PQM. Experiences vary widely however, primarily based on whether the upsell books into a revenue inventory class. My theory is that this will be based on whatever the lowest available inventory is when you buy up, but I don't have enough data to confirm this.
