I believe one can't reapply in the same application year (irrespective of the admission cycle you apply to). For example, if you are applying in round 1, then you need to send the score to a school by the deadline of sending the score to that school for that particular round (round 1). In case you plan to retake and you get a better score, you may need to notified the school to consider that new score BUT all of that need to happen before the deadline date of round 1. So, in short, I feel, what you are saying is not feasible. That's my 0.02$.
