If I were you, I'd get rid of the "right person, the right question at the right time" bit in the application and include "we have shown the feedback overlay more than 1K times and have gotten a 60% feedback rate."
I think for a general investor or layman, the story would be more compelling because it lays out why it is high (and that it is high for the industry). YC would be in the more technical group and would already know this, so just giving them the 60% is more likely to get their attention.
