OK, I'm probably not making myself clear...
Attached below are two scans taken from the Quality Scans thread. Each shows a roughly similar burn - about 20,000 PIE across the entire disc.
One program (Plextools) reports a PIE average of 0.15, while the other program (CDSpeed) reports an average of 2.5, which is over 16x higher.
And neither bears much resemblance to the graph, although the CDSpeed one seems closer.
The original question in this thread asked about the discrepancy between averages, which is something I'd also wondered about. Clearly, one of these programs is calculating averages incorrectly (or based on a totally different criteria) and I'd appreciate any input on which one.
