The bloat factor depends on many things, for example which operating system do you have. For example, the registry of Vista is by default more bloated that the one of Windows 2000.
But you can reduce the bloatness simply by using the Software Manager to remove traces of software you no longer use and by using other tools of the jv16 PT, such as Registry Cleaner.
However, running the Registry Compactor doesn't affect the bloat factor at all. The Registry Compactor reduces the size needed to store the registry data. The bloat factor analyzes the contents of the registry, not the size of the files required to store the registry.
Like if the registry was a bottle of juice. The Registry Compactor can usually squeeze the bottle a bit smaller in a way all the juice still stays in. But the bloat indicator doesn't look at the bottle at all, only how much juice it contains. Hmmmm... I wonder if this example made the issue more clear or less
