Progress bars are very hard. I implemented a PowerShell progress bar in a script I wrote, and even that was hard. The script did a nested iteration, deleting objects and re-starting the iteration. I updated the progress bar based on completion of the outermost iteration, but because of how things processed, the progress bar would move more or less logarithmicly; super fast at the start, but slowing down significantly at the end. I'm sure I could have made the progress bar move more smoothly, but it would have required restructuring my entire program. (It probably needed it, but for a simple script I ran occasionally, not worth it.)
