Thanks for all your replies.
your state authority does not allow you to create your own profiles (you certainly can't do that in Australia)
I am not sure what you mean here ?
Some charts don't even have a published profile so you have to create your own
raise the MDA so that you have enough time to pop out low on the PAPI (after following the database profile) and correct back to on-slope by 500ft.
I suppose that is why the NOTAM raised the minima to the circling minima, for the reason you said.
