Toto Neorest 500 seat height

We have an Ultramax ADA height and love it; we are planning on getting two more for our new house plus a Neorest 500 for our master bath. We are having difficulty figuring out whether, and how much, we should raise the Neorest base to achieve an ADA height for it. Anyone ever work this out?

ADA requires the SEAT height to be between 17 and 19 inches. Get the bowl height, add the height of the seat you will use, then figure where you are.
