That is the thing to understand about how Presidential, VP and ROTC noms work compared to the MOCs.
The Presidential and VP can nominate 10K if the candidate is eligible. However, only 100 can be charged for the President. 5 at any given time, like the MOC for the VP.
The MOC can only nominate 10 per slate, for that 1 charge. So, statistically, your odds may be better on the MOC slate compared to the 2 you have in hand.
It is not going to hurt you because you did not apply to your Cong. from the perspective that the SA board or the other MOC's will mark you down points.
It will hurt you because it would have allowed you, if you received all 3 to be on 6 slates. (Pres. VP, ROTC and 3 MOC) Giving the SA less flexibility to slide you in without going to NWL with only the 5. Still 5 is a lot of slates.
That is why people say apply for each and every nom that you are eligible, because the more you have in your hand the more flexibility for them to appoint you.
Look at it this way, if Candidate Jones has 3(all MOC), he can only go up against those 3 slates, now he maybe number 2 on all of those slates, which means if his WCS is high enough he will go to the NWL. However, had he had a Presidential, he may have earned his appointment via that slate. That one more nom., gave him one more bite at the apple.
Good luck.
