The HAT of 659 only tells you your height above touchdown. Given undulating terrain, there's no easy way to tell your AGL altitude on approach.
The parentheses altitudes are not AGL, rather the following: For straight-in mins (HAT, height above touchdown), which is the difference between MDA and TDZE; for circling mins (HAA, height above aerodrome), the difference between MDA and airfield elevation.
The height above touchdown value (in parentheses next to the MDA) of 361 feet and the profile view of 0.7 miles from brick one (and we rarely aim for brick one) are close enough to meet the performance parameters of most pilots and aircraft.
