" There is absolutely no possibility of making sure 2.8.5 upload has reached 100% from your side. If a 2.8.5 user shows "complete" after half an hour he might have downloaded the earlier or from another host."

I think you should bring back an upload progress bar that works. Same ip connects and disconnects, no aqua in bar to indicate what stage upload is at, and time remaining never diminishes. Even if it is only relative, it would be helpful.

Plus, could somebody explain the way the Library computes uploads? I don't understand the fractions. Say it is 34/78, I would expect as chunks transmit, the first number would increase, but both increase, and often, the first number never catches up to the second number.
Very confusing.
