UNC Kenan Flagler R4 chances?

Is it worth applying this late or am I doing myself a disservice?

Background: I've already secured a couple of admits and am waiting for some decisions in March. My hard stats basically fall in line with UNC's median #'s, so in that respect, nothing spectacular.

I don't really know how I overlooked it when doing research but I basically applied to every other program in that 15-20 range and missed UNC. I feel like it would be a really strong fit for me, but just don't know if its worth the effort this late in the game.
