The really interesting parts are easy to identify as the author did, but one can learn a lot from the boring parts as well.
For example with enough information about ship stores/rationing we can learn about how many ships they had, their travel patterns, a whole map of when they were where, the men involved and their whole history.
Alternatively, if there are suspicious gaps then you might find traces of reports that have been deleted, cross-referencing those to ships/officers that didn't report in as usual you might be able to track them to find out more information, etc.
