I do the same thing for internal analyses when a student has submitted only an SAT score. And if they submit both ACT and SAT, I use the actual ACT score, even when it's higher or lower than the calculated score.

For internal analyses I use the concordance to
create an ACT-equivalent score for each SAT score and use those in
computing an overall ACT average -- which I think better represents our
complete student body.
