I think Albury was the only PAPI that I have flown in to, or toyed with on an approach.
the papi is off to the left of the strip and I found that at a point near the initiation of the flare the papi indicators vanished out of my left side field of view.
In the discussions I've read here there seems to be the thought that the papi is available as a reference all the way to touchdown.
surely this isnt the case.
surely the positioning of the lights means that for all pilots they vanish from view at about the point where you'd flare for touchdown.
they are after all only a guide as to approach angle.
