Include a "Differential Size (KB)" and "Incremental Version Number" as optional Column Choices
"Configuration Manager supports up to five incremental versions of a content set before it resends the entire content set"
"Incremental Version Number" would keep track of how many incremental versions (0=Full through 4=4th Incremental) of a package have occurred prior to every 5th content distribution which is when the next entire data sync will occur.
"Differential Size (KB)" to store the Result of the 'Binary Differential Replication' calculations of 'Source Version X' vs 'Source Version Y'
These two values would be extremely helpful in calculating future bandwidth requirements as well as calculating approximate content distribution times in Low Bandwidth/Packet Shaped environments.
