Is it true that if embryos are PGS tested and deemed normal, that you need fewer of them since pregnancy rates are higher?

My care coordinator made mention that if you’re embryo banking (like we are - first retrieval is in a couple weeks.... depending on numbers we’ll do one more) and have done PGS, that it’s okay if your number of embryos in the bank is lower because pregnancy rates are higher than non tested ones.

Did I understand her correctly? Anyone have thoughts or experiences? We’re trying to determine if we ideally would like two kids, how many normal PGS embryos to bank to feel relatively comfortable with our odds.
