Franky, I think your 5x and max scans are pretty well equivalent, so you may as well save time and scan @ max. I suspect that if you repeated the 5x scan, you might not see the spike. The results vary from case to case even for the same disc at the same speed. I've seen up to a factor of 5 in PI Sum 8 on my LiteOn.
I strongly recommend looking at more than the CD-Speed quality score when judging a disc.
The quality score that CD-Speed calculates is (at present) based
solely on the maximum PIF value. By inspection of my own results and others posted in various boards, the score for
LiteOn drives is derived from a simple polygon through the following points:
- Code: Select all
PIF-Max Score
0 100
4 90
10 50
30 0
I don't know what the corresponding NEC or BenQ values are- based on the shaded tolerance zone, I'd expect the PIF-counts to be a factor 4 higher (your scores are compatible with that). Maybe a NEC or BenQ owner with extensive tests (Ian? D_R?) can comment.
