Slide 12 EMc4 changed nest color. Did nest really have 0% opt out or they just haven't provided data? if so maybe add that commentary to the right. Also maybe note that this is binary over the whole event while the next slide shows persistence over the course of the event of those who stay in the pool. Ezra McCarthy, 9/28/2016
