EDIT: well I know Plus-X is 125 on the NEW standard so does that mean it WAS 64ASA before?

In addition to the change in standards, some of the films changed over time as the technology improved, and those changes included changes in sensitivity.

In some cases, old films were replaced with new films with different names. In other cases the names didn't change.

Like Vericolour, which went from ASA 125 to ASA 160, and was still called Vericolour.

Although that may have been when it went from Vericolour I to Vericolour II (or was it II to III?).
