The average session duration metric is calculated over a week following the display of an insert to a user.
In some cases, the insert can influence overall user behavior in the app. This can happen as the result of onboarding inserts, guidance inserts, and other insert types. For these cases, we provide the average session duration metric so that you can compare the effect of users who saw certain inserts versus those that did not see the insert but meet the same criteria (control group).
