A) The inhibition can be quantified by the difference between measured calcium at the maxima, the delaying effect as the difference in added calcium at the maximum, and B) The missing calcium marks the difference between the added and the measured calcium concentration at the maximum. The difference between the two missing calcium concentrations at the maximum describes the excess missing calcium.
