Google Play Store: How The 'Reduction' Update, Delta Algorithm Makes Better User Interface?

Google Play Store new delta algorithm can shrink Android app updates while making the actual download size of the Google Play Store updates transparent. The Google Play Store goal is to allow users who are sensitive to the size of their Google Play Store downloads to be able to get the latest Google Play Store updates in reduced size that will not compromise their device storage.
