An exception to this is if an unchangeable feature of the product is to be
examined which is independent of the proneness to error and frequency of use.
In this case, the value 0 is given. This results in the following table for the
compression program:
Correct compression

Detection of bit errors in
a compressed file

%
Test time
Comp-lexity
Test depth
Frequency of use
Error-proneness
Confidence factor
Deletion of files only
after successful
compression
