You do realize that that is true about movie block as well right?
How so? Movie Block only handles a third of the journey, but it is generally accurate to the movies at least because of panning between Frodo's journey and everyone else's journey.
The biggest discrepancy would be site 8K because it covers the largest expanse of land between Cirith Ungol,
Morgulduin, and Crossroads. But otherwise, it largely reflects the movie.
