Data Usage Amount Syncing via 3G/4G
 

Can anyone comment on the amount of data being synced using the Omni Sync Server?

Situation: Say I'm on a 4G connected iPad, using OmniFocus for iPad, and allowing it to auto sync. I'm wanting to know if the whole OmniFocus database on my device is being synced to/from the Cloud or if only the changes are being synced. If my whole database is being sent back and forth with every sync then my fear is I'll burn through my allotted data cap rather quickly.

Cheers!
