Hi All I am posting this here so we have a record of it.
Justin McLean posted a note in our Slack Channel that there seems to be a dip in the statistics every 4 years. He was wondering if it is a leap year bug. To replicate 1) Login to Kibble demo 2) Click on Engagement 3) Click Contributor Retention 4) Look at the graph for email retention I took a look and can replicate it. The dips do seem to be starting around the 1st March on 4 leap years 2004, 2008, 2012, 2016 and there is currently the beginning of a dip in 2020. Next step will be to take a look at the data and calculation. Thanks Sharan
