Now I hope I can inject my opinion. In regards to the word 'precision', I would not use the word in regards to disc quality testing that is done on your home PC. The closest we would get to precise results would be in a controlled environment, with top of the line testing equipment, which is being done by the NIST.
The words accuracy and reliability would be more relevant to CD Speed. I have no experience with Kprobe so I can't comment on that. But I have had conflicting results from CD Speed on the exact same disc.

Therefore my question;
What is the main purpose of CD Speed , if for example: I have a DVD copy, one of the first movies I copied, It plays absolutely flawless on the screen even after all this time.
Then I test it on the CD Speed and it comes out at a very low PIE count, so low in fact that I run it again just to see, but the second result almost doubles in the error count?.
Now I know that the disc is flawless and that I recorded on top media and kept it very good care, So why did I test it for in the first place?

The answer is because of all this frenzy about how the disc quality testing will show that our copies are deteriorating quickly. How do you Know, when the test results vary so much from software to software and drive to drive and test to test? Isn't the bottom line that you record on good quality media, take great care in handling your copies, and that it plays like it did with the original?

So in my opinion, while these tests are useful to a degree, it is not the absolute measure of your DVDs.
