I saw an auction recently and the seller listed only the number of the roll. So if you only have the roll number, can you determine the serials of the chips? I think so because I think Satoris were only sold in rolls. The math is simple if all that is true. It would also mean rolls 1-1525 are prefork and roll #s 1526 to 2525 are post.
Prefork 000001 - 030500 or rolls #1 - 1525
Postfork 030501 - 050500 or rolls # 1526 - 2525
I think rolls started after chip 10000
Also, some rolls skipped chip numbers due to production/quality issues
