I guess I’ll say that I don’t really have this as a concern. The projection is “fine” for DL flights as long as there isn’t a ticket exchange. As
xliioper mentions above, CC spend posts pretty quickly. Not sure why I would need to project that to that great of detail. I’m not earning $28001 MQD… even if I were close, I wouldn’t “risk” being that close on something I care about. There is no reward for making the exact minimum.
