Euploid proportion first to subsequent cycle(s)

Raw counts aside, what are the typical expectations for euploid proportion from one cycle to the next?

Just trying to mentally prepare myself, as my first cycle yielded 3/4 aneuploids, 1/4 undetermined.

Had my second ER yesterday, will find out blastocyst count in a week, but honestly won’t exhale until I have the euploid count.
