Answer 1

Some parts of a process take longer than others. For example, duplicating twenty 1MB files is noticeably quicker than duplicating one 20MB file. So if you put those together into a 40MB file transfer, then the first 50% will take less time than the last 50%, and this is reflected by the progress bar.
