The reason for this question is nothing but to make and get it right every time I fly, just for the reason behind things. I've seen so many people's discrepancy over this issue, some set the acceleration altitude eg. 1000' + AAL, the others set 1000'+departure end elevation, and so forth (sometimes, in some airports, it's quite different).
We've been flying for so long with somethings as vague and undefined with so many improper explanations, on such questions as this one that WHY do we have to add it the way it is.
and I think everyone here could definitely help ;-)
