Installation Manager display meanings

What do the stats at the bottom of the Installation Manager mean? The Percentage I take is the percentage of an individual package and the MiB displayed is definitely not the total Megabytes downloaded. The bar at the bottom tells me nothing about how much is downloaded as it goes back to zero as soon as a new download starts. What does it all mean and how is that helpful to me?

Hello,
I moved your question out of Wishlist and into General Discussion & Feedback.

My Installation Manager for the current mandatory update shows 1.40GB on the right side of the “download bar” but the download bar is already showing 9.1GB and counting? It is also showing a percentage as 8735% currently whatever that means? Can anyone explain what is going on please?
