Iterative Progressive Incarnation

Looking for feedback on the concept, “Iterative Progressive Incarnation” (I may have just coined this). In other words, as we go through each iterative incarnation to return to earth for our next round of lessons, would you agree or disagree that this process is progressive? Does each round build on the last so that we don’t need to re-experience or re-learn what we have already done or finished learning (been there done that)?
