Good point. And, as I recall from Welcome to Storybrooke, everyone started out at the beginning of the day, waking up, so that part, at least, is probably going to be consistent.

One additional thought. Belle and David did not have any memories (False or Real) at first. In each case, It took Regina (or Gold) to step in with some specific item that triggered the false Memories. WIth David, it was the WIndmill in Gold's shop, with Belle, it was the Matchbook.

So, my guess is that the curse accomodates general filling in and adjusting memory as needed. Regina's curse defaulted to wiping memory (and was manually adjusted for Jefferson) and giving some either random or predetermined alternate set, Snow's curse defaulted to keeping memory intact with no (or minimal) adjustment needed. The amnesia potion that Zelena added to Snow's curse overrode the memory default, causing the selective 1 year amnesia.

I also think that is how Regina adjusted Emma and Henry's memories in Going Home. They were still within the confines of the curse, allowing Regina to give them "False" memories, which, by the rules of that curse, became in effect once they crossed the town line. We don't yet know the rules of Snow's curse for crossing the line. It may be that everyone can cross and keep thier memories (if they can ever cross the line.  It seems someone keeps putting up a barrier of some type to prevent any crossing.)
