Frankly I don't like how SSS does either: it really tells me nothing about my class except that "You can kill "insert name here". I could kill the "Thordan dummy" with my lowest dps AND my highest dps class. Time was the same. So it means my dps is good? How? It tells me nothing about it and I really found it useless because it only says that I got enough to kill a boss, yeah, but on the best case scenario with no mechanics and my cd done all at once on a burst.

On the other hand, that link is very useful: it might not be accurate, but it definitely helped me to have a rough estimate of my own dps so kudos on whoever made it.
