Jes45,
I would caution any over-reliance on one parameter to evaluate CD quality - in your case, Block Error Rate.
This counts error frames, so it counts 1 if an error frame contains only one bad bit; and similarly it counts 1 if the entire contents of the frame is erroneous.
BLER testing, according to ISO-10149, requires an average over a 10 second interval. This may give a less than accurate indication of quality should there be severely localized degeneration.
There are many CD parameters that are measured to estimate the quality of a CD. If all of these measure well, and the BLER is good, then you have a good disc.
Regards,
