This was an assumption. I'm accepting your convincing rebuttal of this assumption.

By the way, today I measured CC with the highest sensitivity (25 ml sample in Taylor's k-2006 kit) and found CC <0.2 for a FC 4.5 water sample. It's amazing that the pink color for CC <0.2 is detectable.

I still don't understand why the same shocking level needed to kill algae is also needed to destroy CC because I'm sure that one algae cell has more than one or two Cl receptors, so the high level of FC in the case of algae makes sense from a stoichiometric point of view, not only just for kinetics, but if you say that this is a well established empirical fact, I'll accept it by the same way I'm accepting your calculated values of FC needed for preventive maintenance and sanitizing.

As to the other issue of deceit etc. - please wait until I post it and see what I mean.
