The point is that a significant proportion of NPAs are no longer constructed with an MDA. Rather, they are constructed with a DA in the same manner as a precision approach. The likelihood of going below the DA during a go around from minimum is accounted for in the drawing of the procedure.
Not in the NPA TERPS which are designed with a MDA, there is no consideration for a DA. They are adapted to be used for approved operators to use a DA in lieu of the MDA if the approach visual segment meets additional criteria, for example the same runway is served by an ILS. Of course you would fly the ILS if it was in service. Jeppesen adds this information to its charts as an added value. My main point is that on NPA procedures, TERPS does not evaluate the suitability for use of a DA in lieu of an MDA, it is a separate after the fact evaluation performed as a value add product by Jeppesen.
