I thought I was clear, but apparently not.  It is 100% duty cycle for 13 
seconds, and zero for 2 + 15 seconds.  "Duty cycle" is all a function of 
what period of time you choose to integrate over.  Lots of components if 
heavily over stressed can go south in 13 seconds. Whether that is the 
case with the KAT3 is unspecified as far as I can tell.
