It does however put everything in one place in a fairly simple to understand format, and from my reading of it didn't seem to make any obvious errors - seemed to be surprisingly well written and researched.
But it doesn't have everything in one place, it has the same information that scores of other articles have in one place, in one place. So for '"well researched" I would say "well syndicated". Subjectively, some may find that "excellent" but I just find it more of the same. Just saying.
