I had some questions related to the Kodi sync process. By definition sync would mean two way communication, so other than updating Kodi with the artwork in EMM what does the sync process do? What information is taken from Kodi and updated in EMM? What is the purpose of real-time sync?

Real-time sync means that an element will be synced automatically after each edit or rescrape. Whitout real-time sync you have to to that manually via context menu in Ember.
To only thing that will be synced from Kodi back to Ember is the playcount (watched state) and lastplayed, but only if you have set a host for playcount sync in settings.
