At the moment there a 3 versions of this SafeKeeper CD-R, and they seem to be made in different factories as the OverSize capacity varies alot!:
Made in EU
Made in USA
Made in Taiwan
The OverSize Capacity of 79:29 minutes seems to be a "phantom" value. Feurio! has problems trying to get the OverSize Capacity for this CD-R. Out of 8 testruns, 2 resulted in values arround 79:29 minutes and 6 arround 78:31 minutes.
