Possibly....(I'm not sure WP's definition of "all steps clear," because in the view of the candidate, all steps might be clear once they receive notice from the MOC)
I'd agree that if a candidate has a nomination source OTHER than a MOC and has an LOA, then the charging could be a simple clerical function. This is simply because they have met the LOA conditions (presuming they are fully qualified).
If the candidates doesn't have a nominating source other than the MOC and they don't report the slate until January but notify the candidate in December, then the appointment isn't coming 1-2 weeks after...so just because you might be notified that your MOC nominated you (again presuming you don't have have another source of nomination, i.e. Presidential, JROTC, etc.) then I wouldn't necessarily say that you are guaranteed to hear anything shortly after, but how/when MOCs submit their nomination is on a MOC-to-MOC basis. In cases of multiple MOC nominations, an offer of appointment is likely to be made once the quickest MOC reports their slate.
So you could hear shortly after OR it might be longer. Hence why I say you can't put a definite timeline.
