I didn't notice that, it's very interesting. Do you remember? Once we wondered if the +600 average read offset wasn't caused by the glass master cutters inserting a null sector at the beginning of track one, offsetting our measurments by +600.
From the opposite point of view, it would mean that the real average read offset is 0 and the burners all insert about 1 sector of null data (588 samples) at the beginning of their job (average write offset=+600).
In that case it would maybe be more secure to read with a zero offset, as the CDs are made for, to avoid cutting any data at the beginning by accident, and to burn with +588 write offset to get a clone (since the null sector is already into the wav, no need for the burner to insert it again) . In other words, to add +588 to all write offsets and -588 to all read offsets.
On the other hand, people would start burning mp3s with write offset correction, which would be a bad thing.
