Follow the ILS or VOR,DME,NDB to MDH (MDA) as applicapple. When visual, use the PAPI's as a guide, but remember back to your first lesson as a pilot. If the 'picture' looks right, then it is right, and land. If not, go around.
No need to discuss various glide angles, PAPI 'eye hieghts', aerodromes set for certain aircraft types etc etc.
We are trained to land our aircraft as hands on, eyes out, capable people.
Fly the aircraft, hands on, eyes out, isn't that whats it's all about?
