This suggests two possible methods for improving the accuracy in esti- mating pQ values with these methodologies: (1) increasing the number of data points by decreasing the quantity ... given data point and the two data points preceding and following the central point. Average effective pQ values can then be calculated by averaging the values ob- tained from twice sol...
