Status tier earning usually does not have a multiplier. Usually completely different system, that often has with little relationship to total distance flow or class.

As above ffp miles are not equal to earn or burn. 10,000 ff miles may get you a longer award flight that 12,000 ff miles in another ffp. And status earning is not always the same
