In the end of the day, it is not about NMF to gain admission. It is about the competition for the nom, thus, even if Delaware is high on the NMF cut off point list, that has no bearance to the amount of people applying for a nom.
Delaware is not seen as a competitive state regarding noms when compared to CA, CO, FL, MD, NY, TX or VA.
What makes a state nom slate competitive is the amount of candidates requesting a nom, additionally another factor is if the MOCS "talk" to each other...aka spread the wealth theory.
For example, NY has a "spread the wealth" theory and even goes as far as to say if you have received a nom from another MOC, you are to remove your request for that 2nd and 3rd.
I don't know about Delaware, but if the MOCs don't talk it is possible that a DE candidate can get all 3 noms, whereas, the NY candidate can only get 1. The reason to spread the wealth is that there are too many cadets that request noms. and not enough to give. For example, our friends DS in CO wanted USNA, placed it as his 1st choice. He got a nom to the AFA. He only got one nom. That is why people say CO is competitive.
Quick way to find out...call the MOC and ask traditionally what is the number of applicants they receive?
Additionally, DE slates compete against each other for the nom and the apptmt charged to the MOC. Now, if the candidate on the slate does not win the nom, but is very competitive with their WCS they will be put on the National List. That is when your academic record would come into play against the other candidates. I am thinking you are under the assumption that you get a nom from DE and then compete nationally, thus the NMF comment.
