That looks very good to me. I don't know what the huge line in the middle is though.
It looks great to me as well. Keep posting results like that, aviationwiz, and you will make us all Plextor Fan-atics.
Here are some pressed DVD results:
Pretty ugly, huh? The spikes seem to be somewhat common. I don't know exactly what they are, but my suspicion is that they are hiccups in the measurement process and shouldn't be attributed to the disc quality. I suspect this because they seem to shift in position from test to test on the same disc in the same drive.
Your Plextor result also looks good in comparison to the Lite-On LDW-401S, Optorite DD0203 and Sony DRU-510UL results dhc014 posted:
http://www.cdrlabs.com/phpBB/viewtopic. ... 5377#75377I must mention one caveat: my results (and dhc014's as well, I think) were measured on a 166S, while yours were measured on a 163D. I don't know that there is any difference between the two, but there is at least a possibility that there could be. It would be nice to do some testing of the same disc on different drives to see how consistent the measurements are.

Oh, how quickly they forget:

By the way, I think most people are using the KProbe default of reporting the errors for 1 ECC block. Everyone should use the same measurement method, if possible, to ease comparisons. And I think that method should be to report the errors for 8 ECC blocks so that it is most comparable to the PI standard. Unfortunately, reporting for 8 blocks isn't the default of KProbe, and I suspect a lot of people don't realize the setting can be changed and don't know how to do it. Here is how:

The other unfortunate thing is the summary header saved with the KProbe results file doesn't indicate how many ECC blocks were summed over for the measurement.
