Response Drifts Over Time


Purpose:

To establish that the hypothesis by the ATC/CFS, that any drift in instrument response (what Hodgson describes as significant drift in accuracy and precision over time) will always be caught by a single point control test, is not supported by any empirical study.

To establish that there is no study abstracted in Wigmore on Alcohol that establishes the ATC/CFS hypothesis empirically.

To confirm that the new calibration curve created after a re-calibration compared with the old calibration curve prior to recalibration can move up, move down, move sideways, or rotate in either direction around an axis that may or may not be at 100 mg/100mls.
