cycle, cooling etc.

Ralph, ultimately what you're looking for is to run the amp at 1/4 the
maximum  CW output of the amp. In other words, if the amp runs 800 W output
on CW you want to drive it to only 200 W output max.  This allows for proper
headroom for modulation.
Otherwise Eddy's guidelines are correct.
