Not at all. See NEC ND-3540 vs. Plextor PX-750. The percentages represent the good sectors (green) vs. the unreadable ones (red). In the green zone are also included the corrected sectors (
ie sectors that were faulty but the drive used the CRC algorithm to recover the valid data).
As long as one uses the same drive to check the discs, no problems, s/he has at least a reference. But combining data from various drives, with various discs, and various programs (I use Plextools and pxscan, some use KProbe, other use CDSpeed and so on) is not a good practice IMHO.
