Why is Impression's estimate for an incremental backup as large as the estimate for a full backup?

Impression's preflight estimation engine measures for the total file count, the largest recorded file in a backup set, and the total size of the folders/files to be backed up. It doesn't estimate files to be excluded, which both affects incremental and grep-based exclusion engines. Rest assured, as the backup session runs the disc use estimate will be dynamically adjusted downward as items are encountered and excluded. In this case, the estimate provides a 'worst case' scenario, and then adjusts the estimate downward during the course of the backup as it runs the course of the session.
