I can't make any sense in this. I can't think of any reason not
to cut your flash power when conditions allow.
When shooting at ISO 50 you're reducing your camera's dynamic range by a stop. Maybe that's not big deal. You'll have to do your own testing and compare shots.
Ideally that's what you want to do.. but say you have a light boomed up 15ft and it's not hooked up to an intelligent trigger, and after you meter it's higher than you though, requiring you to stop-down more than you want for the DOF.. I'm not taking it down and changing the power, I'm dropping to ISO 50 and going from there.
I can also get into a rhythm with a model in the studio and when things are really flowing, the last thing I want to do is kill everything and say "hang on, I gotta stop the shoot and adjust the light over here for a minute, then re-meter, then change it one more time.." etc..
A lot of times 1 stop of dynamic range isn't a big deal. Simple fashion shoot on white seamless, muted color clothing, not too much texture.... I could care less about that stop in dynamic range because the image is going to look the same as far as dynamic range is concerned at 50 vs100.
