RFM can't take those situations into account. It just adjusts to even things out based on history.

Which is where Flex Lists can be very effective. Let's say ABC has a disasterous return rate this year when in years past it was amazing. Flex List + gives a pre-approved list of PNMs that the chapter is willing to invite back, i.e. more than the number Panhellenic originally said could be invted. Or vice versa, XYZ historically has low(er) return rates and this year has dramatically improved. Flex List - is a pre-approved list of PNMs the chapter is willing to cut, i.e less that the number Panhellenic originally said.
But it is only possible to use Flex Lists with Preferential Rankings, not traditional accept/regret. PNMs finish a round and immediately go rank the chapters they attended. Panhellenic can see if a chapter has been ranked higher/lower by more/less PNMs than in past years. They can then adjust the invitation numbers accordingly using the Flex Lists before invitations are actually extended.
