Why do we need data this detailed in order to get a good enough idea of churn rates? What if e.g. we pinged on the first open every week; if someone didn't open the app that week, no ping. The distance through the week could give us a bit of a proxy for frequency of usage. I think we could get a good idea of which channels were better, without tracking every app open by the user. In general, I think we should always be thinking "what's the minimum amount of data I need to collect to get a good-enough answer to my question". Did we approach this from that perspective?
