Hardness and alkalinity are both in mg/L as CaCOā, so they compare directly; grey numbers are worked out (hardness from Ca + Mg, alkalinity from HCOā).
The label gives typical values; each measurement is one sample, so they differ a little. The Water list uses the label, and a measurement only where the label says nothing.
