Why Is the Sent Count for Cards Drastically Low Compared to Push?

Problem

The sent count for Cards is drastically low compared to Push.

The following table shows the difference in the sent count between Cards and Push:

Cards Sent Count	Push Sent Count
Calculated based on app/site opens. Card sync and delivery events occur only when the user opens the app.	Calculated based on push reachability.

As card delivery depends on the user opening the app, the sent count for cards is lower than the sent count for push notifications.
