It really depends on the situation.

Obviously blindly going out and sampling your water without involving your other senses is not getting to know your pool. But for those times when one's unsure about what's really happening, I'd like to be able to say, 'ah, CC's dropped to 0 so I know now I can move from the Cl to attend to what is really acting on the water'. I think anyone who's homebrewed beer can appreciate this.

But... really? Algae's growing, CC=0 and (I assume) FC is high? I'm definitely not doubting you, but it kind of goes against what I've learned here.
