Publication or significant number of grades. Since you had no previous research before, maybe you could update if you ever present research. I mean 100 hours is like, what? 2.5 weeks of working? Closer to the end of last cycle though, I just Hail Mary'd and sent update letters everywhere. Might work for you, but definitely did not get me off any wait list. That was updating with MD letter of recommendation and 4 months ish working as a scribe.
