The conclusive and geometrically correct way out of this is
a) figure out the distance of a 3 deg aiming point (300 m or my type)
b) learn to read the different markers and standards to identify the physical location
===== the result just cannot get any easier =====
Field guide A320:
Fly the plane at the front edge of the 2nd marker.
Field guide A330/340
Fly the plane at the far edge of the 2nd marker.
===== if your antenna is within 3 m from pilot eye, use the same ======
(note the absence of any reference to PAPI or GS, FAA or ICAO or other's regulatory reference and runway length considerations).
