You could actually program a progress bar that works very smooth. Just let the progress bar progress up to 50% while the machine is doing its work. When the work is finished, remember the time it took, and let the second 50% of the progress bar be done by simply increasing the progress bar while doing nothing. This way the bar will be very smooth until the end. It will take twice as much time, of course, but it will be very smooth.,(reply>), And it would be yet another way of lying to people. Apparently that is what this is all about: Insisting on showing something even though you cannot make it correct. Lying is better than saying nothing.
