I'm a little confused with Backround App refresh. A few apps that I'm using, such as Pocket, have it enabled, however if I launch the app, the articles I had saved to "read later" are downloading. How often does BAR pull the data in the app to keep it up to date?
When Background App Refresh is on, apps that take advantage of this feature can refresh themselves in the background. For example, an app can check if new content is available and download the updates, or retrieve the updated content in the background when it receives a push notification, so the new content is ready for viewing when you launch the app. Apps can also schedule background refreshing based on your location. iOS learns patterns based on your use of the device and tries to predict when an app should be updated in the background. It also learns when the device is typically inactive, such as during the night, to reduce update frequency when the device not used.

There's no way to tell what the schedule that Apple is using to refresh the app or force it to happen more often?
No, there isn't any way a user can see this information nor affect the scheduling. All you can do is turn the option off, either for a specific app or globally, in General -> Background App Refresh.
Regards.
How exactly does Background App Refresh work?
