The language in the report is not clear, whether 80 minutes later was when they started rescuing or finished rescuing, or what the 80 minutes was after. A person would need some concrete times for various events in order to know what they mean. It sounds like the report itself is just reiterating what Kawasaki said had happened.
So we’re stuck with the possibility that someone leaked the contents of a sealed document before the court in Seattle in which dear old deceased Fuddy was mentioned as a possible witness related to the ongoing saga of the dubious identity of zero...and she was left in the water with her companions for an undetermined amount of time, maybe for an hour and when the rescuers did arrive, they saw she was unresponsive and just passed her by and picked up someone else first...is that how it goes?
