Yeah, just do 100 and see how high it can get.

Mine at most goes 40... but it doesn't matter too much.

Reboot the computer, do not launch keyclone, launch one instance of WoW, set it to 100, and still get 10 or 11... then something else is doing it.

If you're trying to launch multiple instances of WoW, then do the above, and see when your FPS goes low after just 2 instances... then add another one... set it to 100 ... Eventually, you'll know where the limit is for your computer.
