It's subjective but IMO grouping does help. It's not that the icons change positions regularly. There is no need for that. If you install or remove an app you may need to rerun the algorithm. But even then, the icons rarely change pages since they are still bound to the colors around them.
Usually, when I need to find the app, I already know its color. So I navigate to the page of that color and find the icon there.
But now that you mention it, it would be fun to reverse the metrics so each icon pushes similar icons away and see what we end up with.
