Another thing to consider - Is the 34:1 “clear” from MDA (DA/DDA/VDP) to 50ft above the landing threshold? A few years ago, FAA TPP added a light grey “stipple” symbol on the profile view of the plate. This indicates that the imaginary 34:1 surface is clear of penetrating obstructions. Flight Check verifies this during their periodic inspections.

Absence of this light grey “stipple” symbol on FAA plates means “look out below” and make sure you visually follow the PAPI or VASI (stay on the PAPI/VASI glidepath). Hence the reason that many chart notes specify “VGSI Not Coincident”. Translation: Remaining “on path” using VNAV guidance only might be hazardous during some non-precision procedures.

Also please note for awareness that Jeppesen Does Not Currently Publish this same “stipple” symbol/feature on their products. For more info, see the AIM and related AVWEB article on this a few years ago. If I can dig up the link I will post it here:
