Is the harvest based upon this current incarnation or is it cumulative?

This question was posed on the Facebook study group and it intrigued me as Its not something that I ever considered. 

For the 3rd density natives, does over all karmic balancing, lessons learned, etc determine ones harvestability or is it simply this incarnation? I'm led to think that since this current incarnation is a culmination of all prior lessons learned, the last incarnation one experiences would indeed be the deciding factor. 

Does the choice of being of service to others or self the only determination or does past karmic ties factor in to this?

Here's how I think about it, but I don't know whether I'm correct or how confused my correctness may be.

It seems to me that the "self" doing the advancing is something below the surface of the momentary personality of an incarnation. Because we're in space/time right now, our concept of a "choice" is usually tied to some discrete chooser and some discrete event, where an entity is undecided beforehand and becomes decided afterwards. But those of Ra speak of the choice being something far less phenomenal and momentary, and that by the time we're aware of our polarity, the choice was made "long ago". This implies the choice spans lifetimes and encompasses more than just the consciousness we access now. Not only that, the choice seems to be something that violet-ray has a strong bearing on, which implies that it's attuned to a total soul-level determination far beyond our current third-density position.

That leads me to believe that the degree of polarization is the sole determining factor and furthermore that karmic ties are only impediments to harvestability to the extent they represent flaws in the purity of the choice. Karmic debts seem directly related to polarization, as they represent opportunities for polarization as yet untapped to their fullest extent, either by energizing them negatively or by forgiving them (energizing them positively). So I see a lot of unity in polarization and karma, with the latter representing a more immediate instance and the former representing a broader dynamic.

EDIT: That argument opens up the possibility of balancing karma after harvest, which I want to say Confederation sources have mentioned before. The other possibility is perhaps people are harvestable but choose to return to third density to fulfill their karma anyway.
