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?

I think that at this point the momentum of an entity's incarnations is essentially set in stone. If that means that the momentum has been variable, i.e. fluctuating between polarities for the duration of the soul's career, then it is unlikely that the entity will attain harvestability now. But if the momentum has been at least fairly consistently directed in one direction or the other, the entity is likely to achieve harvestability.

Therefore this incarnation is both the deciding factor and the product of all incarnations leading up to this one. But there's not much room for switching directions or gaining significant momentum for this one, from what I gather. That's not to say that there aren't currently people who actually are of positive polarity but don't show it - I think there's quite a few who are like the volcano, so ready to burst open, and WILL burst open, it just will take some inevitable last crack of the shell to do it for them.
