'Get back the most useless performance index in the history of Windows ever'
It is, and even MS understood that which is why they removed the GUI and easy access to it. It caused much more confusion than its worth, and was never intended to be a benchmark to compare with other systems anyway.
It was intended for users to compare before and after performance on the same computer - before and after hardware changes. This is why, as new technologies were adapted, the scoring changed as well. For example, when SSDs became commonplace, it was common for users disk scores, and often over all Base scores to drop. Users complained because they did not understand why their scores dropped. Many thought there was something wrong with their systems when in reality, nothing changed.
If you look at all of the scores in the screen shots above they all (except the OPs) show disk performance is the determining factor for the Base score. While disk performance is certainly important, depending on the tasks you typically perform, disk performance may negligibly impact the performance of those tasks - especially if you have gobs of RAM installed.
The program is not worth the disk space it occupies.
I'm surprised anyone even took the effort, nice find
