between first and last identical scans The
number depends both on the bar code quality

Evaluation
The decoder calculates this value as follows:
(a x MG

) - (b x CGM)
MG

= —————————————
(a-b)
a = 63
b = 1
(63 x MG

• The average value provides a trend indication
for the reading performance of the CLV from
