i read some forum post today that the cooldown is less then 3seconds
so i decided to write this little addon to mesure the time between procs.

i have not tested it so if you get any errors let me know.

the timer starts on the first wf hit.
im not sure if it would be better to start the timer on the 2nd hit
and stop it on the next first hit.
the time between the 1st and 2nd hit is probably so short
that it doesent matter.
