When you copy two files (or two set of files) from or to the same disk separately, so that you have two copying progress bars and estimates and the one copying process is dealing with a amount of data larger than the other, nautilus calculates the estimate as if both copying processes were going to be running simultaneously until copying is complete, which is not true. Once the smaller set of files finishes, the larger one will get it's full speed back and finish sooner than the first estimate actually predicted.
My suggestion: Nautilus should be aware that the second file copy is slowing the first one down, so it should calculate the first's estimate as something like: <estimate for the smaller set of files copy to finish> + <estimate time to copy the amount of data that will be left when the second process ends at both processes speed combined>.
Although this approach may look too simplistic, I think it's better than the rather pessimistic approach we're using right now.
