Agree to disagree
Words of an adcom, schools have the ability to sort amcas applications according to what is most important to them (eg. MCAT close to their average matriculant). I have a feeling they can even sort by keywords used. Kind of like how companies can search to only pull resumes with keywords they are interested in in online employment databases that hold thousands of resumes. NU will probably use all features available to cut to the chase quickly. Doubt date of submission will matter within the first couple of weeks.
