Can something be added to Clonedvd?

I was wondering if you guys can add current read and write speed? When ever a Movie finish, I always kinda esitmate what the read and write speed was. Sometimes the end time is a little different by 1 to 2 minutes even if the file is the same size and I often wonder why. Maybe im a little spoiled by other programs for having that feature, just asking if it’s possible to add.
