What happens if I miss to incorporate updates or incorporate updates multiple times?

I am thinking, that it could well be that perhaps my backend misses some updates or, on the contrary, it receives the same update multiple times. Also, the order might be corrupted.

Could you tell me, which of these would pose a problem for obtaining the “real” document and how much the damage would be, in particular, if I proceed with “regular” updates? :grinning:
