How much is acceptable for VAF (Variance Accounted for) in CATPCA analysis?

I used optimal scaling analysis and set 2 dimensions for the variables, with VAF of 36.6% obtained.
I set 3 dimensions, it's around 46%.
I don't know how much VAF is acceptable.
To me, 2 dimensions is easier to explain and define the dimension.
