== Background
- Now that the A/B test bucketing is finished, we need to fire events based of the instrumentation spec T378103 and work investigating the session tick schema in T380926 https://docs.google.com/spreadsheets/d/1tYYRsxICotHT_uAt0gfZckHNZBmqZTKuykeUEwQSCvs/edit?gid=0#gid=0
The session length instrumentation is here

== User story
- As the web team, we need data from our A/B test to make the most informed decision
== Requirements
- Events are fired for session length and click thru rate based off [the spec](https://docs.google.com/spreadsheets/d/1tYYRsxICotHT_uAt0gfZckHNZBmqZTKuykeUEwQSCvs/edit?gid=0#gid=0)
== Design
- none
== Acceptance criteria

== Communication criteria - does this need an announcement or discussion?
- no
