REPLY: 
Aren't Eimac's data sheets for 100% duty cycle? I don't have an exact value for
RTTY contesting but I would guess the worst case is a string of unanswered CQs
at around 80%. 

I agree however, it wouldn't hurt to drop it back to 400-500 watts RF out or so.
At the receiving end they probably would not notice the difference.
