The risk of running just kind of a broad report on retention is that if you average everything out, what you're going to miss are some false positives and false negatives. What i like to do is break out retention by channel and even by source, maybe even by campaign,. Even usertype or persona, if you want to get more specific. Do you guys look at this as well? Yes, yes, we dod and not only do we look at this on a chart, we actually plot it out.
