PIE/PIF scanning is not supposed to be an end-user feature, and is never mentioned as a "feature" in the documentation for customers. That's partly because there are no sound, reliable standards for reporting PIE/PIF with end-user drives, unlike professional testing equipement that is calibrated to be complying with ECMA standards.
Also it was never supposed to be a feature for end users, because what's reported makes absolutely no sense unless one spends lots of time in searching for references on the web. The fact that CDSpeed incorrectly labels the tests "disc quality" and reports a "quality score" (which is highly questionable) played a huge part in the confusion around what is PIE/PIF scanning.
As for you H22N and burning speeds, rest assured that it burns MCC004 extremely well, up to @18X. To be on the safer side, just stick with @12X burning with these discs and you're good.
