Does anyone else see badly flawed logic in the way the ADA angled sink cabinet is set up?  

This formula right here for the top facia height does not yield ADA compliant settings:

=IF(Height-i2u(27)>G!Default_Top_Drawer_Front_Height,G!Default_Top_Drawer_Front_Height,Height-i2u(27))+IF(Enclosed_bottom=1,Thickness_Bottom,0)

Basically, that formula says "If height minus 27 is greater than your default top drawer front height, then use your default top drawer front height, and if you turn on the bottom, add the bottom thickness to that."

If you're going to formulate the ADA knee clearance, it needs to evaluate to 27" as a default to start with, at a minimum.  Currently, the Knee Clearance has a formula of =Height-Top_Facia_Height-Top_Reveal 

BUT....the Top_Facia_Height formula itself is not incorporating the Top_Reveal, so you wind up with a false front that's too tall by the dimension of the top reveal, and an ADA knee clearance that's too short by that same distance.

Then, as shown in the screen shot below, turning the 'enclosed bottom' on makes it worse.  Turning the bottom on or off should have no bearing whatsoever here.
