uhmmm, you obviously failed to understand
the reason why chlorine/chloramine concentrations vary is because chlorine readily dissipates into the atmosphere, that is why they developed chloramine, the sunlight can't break the bond as fast so it stays in solution longer.
The uncertainty comes because of that propensity to dissipate AND water municipalities working to counter that by regularly adding more to the system, so without dynamic testing, you never know the exact concentrations in your tap water.
+1...I think I mentioned variables in municipalities in my first response...post #24
