Not to draw too fine a point, but just a tweak: It's important, when choosing when to enter which credit, to enter them conscious of the effect they will have on the next "earn by" date if you have several you're playing with -- if you care. Otherwise, it doesn't matter when you enter them. The earliest (by earn date) will trigger the new "earn by" date.
Actually, the bind still may be in the cheese somewhat, as it also will affect the one-year "earn by" dates for Companion Pass and A-List status.
Too fine a point... and probably already more than obvious to the "regulars" here. As someone commented when I brought forward "another way to upgrade to A", my head's starting to hurt.
