Where an actual read is submitted following an estimated transfer reading, if the Actual reading is less than the estimated reading a negative volumes is created (the actual read validates to the last Actual read recorded so the period last actual to estimated transfer read would be a positive value). In the instances where the estimated transfer reading and the Actual read are the only reads considered for the AQ Calculation the AQ will be re-calculated to 1, if other reads are considered within the optimum or sub-optimum period for the AQ Calculation the AQ may still be incorrectly calculated resulting in a reduced AQ.
