    be updated. The widget's size may change between calls, but the widget may
    display incorrectly if the size changes drastically and repeatedly.

    Uses a weighted average of two estimates:

      2) ETA based on the progress as per tha last 10 update reports

    The weight depends on the current progress so that to begin with the
    total progress is used and at the end only the most recent progress is
    used.
