The Plextor PX-716A with firmware revision v1.08, showed decent performance, as we can see in the chart above. Something to watch out for later, is whether the high PI Sum8 counts, for the third, fourth and perhaps the seventh measurements, will lead to POF errors, although the peak value is less than the acceptable 280.

There is an issue here with the Ricoh JP NR03 DVD+R disc, with a PI Sum8 count that reaches 880. The Ritek R04 disc was also difficult to read/measure. We did not manage to get measurements for the first three points, as well as the last. The Daxon 016s DVD-R as well as the MCC 03RG20 DVD-R discs, also reported high PI Sum8 counts at different areas.

In case you are wondering, the CMC MAG M01 DVD+R and CMC MAG AM3 DVD-R discs are missing from these graphs, but with a promise to be included in the near future.

It is surprising to see POF in the case of the Ritek F1 DVD-R disc, since while the POF is located in the same area where we had previously measured high PI Sum 8, the PI Sum 8 count was well within limits (see first graph on this page).

The Ritek R04 DVD+R disc's condition could be considered as bad, since we were not able to take measurements at all points on the disc.

The Daxon 016s and the MCC 03RG20 discs also reported POFs, with the errors occurring at the same point where we had maximum PI sum 8 counts in the corresponding graph previously.
