Hi, Tyler. Sorry I'm not being clear.

I'm not saying that 760 users for an add-on is large or small. I have no 
idea. I'm saying that an uptake rate of 760 in 13 days from a total 
population of "thousands" seems impossibly high to me. (I also gave a 
numerical model to make clear why I think that.)

My explanation for this is that the total population of potential users 
is much larger than thousands, which suggests the impact of this change 
was substantially undersestimated.
