That sounds frustrating. Why don’t you reach out to the 8 people , introduce yourself, and ask them if the reports are helpful, ask them what they do with the information, and help you to understand how it fits in with their goals/mission. Perhaps they will tell you they also don’t understand why they are producing what they are producing, but perhaps they will have something useful to share. Either way, they will not be strangers anymore and you may learn something.
We are at the point where the work you describe will soon be generated and distributed by a program, so you will be well served to learn about things beyond the reports themselves.
