Being a person that writes many research articles and the sheer scale of this report being hidden from public eyes, I can only give a outsiders perspective answer.
Every teacher I’ve ever had would expect 10% minimum of the number of pages in the main reports whether it be media, government, fictional, or scholarly reports.
In this case 30 pages would have been more appropriate. It lessens the speculation of skimming and cherry picking that way. I mean some democrats are going to go full tin foil hat anyways and nothing will change that.
Just my opinion though.
