I must echo the other reply: the "delta" phrase communicates far more than the "simpler" rewording does, to the point where the simplified text reads as little more than meaningless marketing fluff. Perhaps it would be clearer to word it as "Between your current understanding ..." instead of "In the delta of your current understanding ..." But keep the rest the same; it's a beautiful sentence.
