Further explanations about the test procedure can be found here, so here are the facts about the PX-W5224A:
As with the PX-W4824A, I was able to examine the test procedure with c2extract to get the C2 graph.

Conclusion
The Plextor PX-W5224A seemed to have some problems with the used test disc. Often it refused to rip at higher speeds than 4x whatever speed was chosen in EAC/PlexTools. But on some rare occasions, it ripped the disc with the speed which was expected. But quality-wise (based on the "Total Test Results" numbers) the drive reached nearly always the same score, thus I've only provided the most interesting details above.
Compared to the other Plextor drives tested so far, the PX-W5224A couldn't reach high scores at all. Even lowering the speed (automatically or manually) does not result in better results.
