The problem is that its more of a scheduler. In order to run the test, each user would need to have at least:
The same version of photoshop,
The same version of Dreamweaver,
The same Web Browser build,
The same Starcraft II install,
The same WoW install,
The same Virus Scanner build,
The same Visual Studio 2008 build,
ect...
There are just too many variables when run on the users side when compared to something as simple as AS SSD.
