Changing SFRplusTest::ParseOverlay to use the 'Secondary_readout_1_outer_quadrant_mean_min_min' and 'Secondary_readout_2_outer_quadrant_mean_min_min' pass/fail keys instead of
 'Secondary_readout_1_outer_mean_min' and 'Secondary_readout_2_outer_mean_min' to avoid a discrepancy between the QSO output and the overall pass/fail status. Cosworth reported
instances where the unit would pass although a QSO indicated a quadrant had failed. Using 'Secondary_readout_2_outer_mean_min' proved to be the culprit as it is meant to be compared
to the mean of all four quadrant results.
