Thanks for the info! So question: how do the CN get assigned? we know two facts: (1) they are not consecutive (2) they are assigned sequentially per each region.
So why are they not consecutive? one of the members of this forum (sorry, can't remember who...) suggested the following (theory):
A selectee receives the next number [n] for the region and if there are [k] others listed in the form (wife, children), then numbers [n]+1 to [n]+[k] are skipped.
To me this makes lots of sense. Case number [n] means the [n]th potential visa for the region.
So to estimate the max CN for a region, we need to know the 'factor' for that region. From official publications, we know that for Asia there were 1,055,433 participants and 807,736 Spouse & Children. So the factor is 1.77.
Meaning, according to this theory, for 16,000 selectees from Asia we would expect CN up to ~28500. Yet largest seen is ~12,000...
I find this odd, unless the other theory has some truth in it: not all SN were made public. Some selectees were not (yet) informed...
All this is just a theory, meaning "an assumption that can be refuted" so I guess that il faut que nous eussions un peu de patience
