To get no-nonsense results, the drive must performed as Philips laid down the specs. The standard requires a single beam single-speed (the ONLY speed back then) Philips optical pickup among other things.
Then and only then, the results would mean something and they will also be reproducible and comparable with others and, of course, with the standards. Only then 134 C1 would mean something.
Very few drives can actually provide this level of confidence. One of them ids the Plextor 40x (SCSI) which is BTW also used, with a modified firmware (to provide a few other parameters) in the past in industrial testers.
Now, let's suppose, for the sake of argument, that one doesn't need the perfection, and he needs only approximative results, like one wanting to know the voltage of the mains doesn't need the "Fluke"-perfection, but may consider a gas-station-AVM.
The difference is that the cheaper AVM still is calibrated, whereas a drive is not.
The drive is designed to give the best results at reading (and hopefully by burning) not to assess the quality.
Therefore, a lot of idiots in the past started to "poison" the optical recording fora, by suggesting people to get
eg LG burners for testing, arguing that they are better (the best, actually) readers than the crowd.
Why idiots? Because it's even worse - to be convinced that you have a good CDR/DVDR when you actually have a bad burn, but the LG can read it, for being a better reader. As long as the CDR/DVDR is played in another, regular, drive, the magic disappears like the smoke.
The PX40 is only an average reader.
In fact, people should use the WORST reader, because if the worst reader can read the CDR/DVDR, then ALL OTHERS will do the same
Therefore, in this case, a simply WRITE/VERIFY would suffice.
