Which doesn't exactly make your previously claimed "official stance" without authorization any more "official", right?
No.
We had that already here. The "not actually cast twice per day" used by unverified David Chart here is a colloquialism used in a private message exchange. It tells you in a friendly way, that a persisting constant effect (from ArM5 p.99 box), namely HP p.101 The Rising of the King, remains over sunrise and sunset controlled by the ghost via HP p.97f Passing the Reins of Corpus.
It does not even address the number of castings needed per day in ArM5 p.99 box, or other conclusions of Constant Effect Devices which you are so eager to draw. You still haven't got it in context - showing thereby, why your claimed "official stance" was in serious need of checking by David before you made it.
Cheers
