Well, I'm not a statistician, and I'm not sure a stats expert would know, in that there are so many variables to contend with.
But I'm inclined to say "not necessarily." On one hand, in a mega sense, the closer one gets to 15 April, the fewer spots remain available. Reason for concern.
Conversely, there is substantially less competition for the spot you are seeking come 15 April. Thus statistically speaking, your chances might be substantially better than previously.
Here's one scenario ...suppose you are #2 in your MOCs ranking. And you've not been TWEd because USNA has not heard from #1, who's been waiting to hear from USMA or Princeton. Or maybe USNA is waiting on a medical situation on #1. And there are numerous such scenarios.
Which would you prefer? Half empty? Half full? Right now you're in total control of which you'd like to believe. The essence of your POV might be determined by knowing which pool are you still in? MOC/Senator? Or the 3Qed National pool.
There is only one thing you can do to impact your possibilities at this point ... Screw up in school. Get in trouble w/ the law. Injure yourself. Contract an STD. And any/all of these will eliminate you. Nothing you do will enhance your selection. You've done it all. Relax.
Bottom line ... Your fretting is understandable and totally inconsequential. Adjust your attitude and practice patience, which will serve you however it comes out, while worry won't do anything but waste your time and emotions. You choose, you determine. Which is it?
One final thought: There is truth in the adage that "misery (and the miserable) love company ..." It seems reasonable that you are seeking company. Yes? Recognize it's your choice to be miserable. Choose otherwise.
