I stand minorly corrected. Crunching the numbers, 3.03° from LENIZ to 53ft over the threshold takes you past GRZ NDB at 2267ft and GRZ VOR at 1592ft.

So the designers seem to have forsaken a steeper angle to achieve the MDA by the MAPt. Perhaps it is because, while you were at the MDA at the MAPt, you'd actually be 92ft low on the 3° slope, at only 412ft AAL. That would probably put you too high to be stable.

If confronted with low cloud and good vis underneath, I'd be VSing it down when past GRZ NDB in the hope of breaking visual at the MDA before the MAPt, just below the charted slope.

If low vis is the issue, I'd just run down the 3.03° and accept that I was never going to get to the MDA by the MAPt.

Fixed.
