The document is a useful framework for you to do your own calculations - you can get the source data from the AAIB report, etc and do your own plots.
If the average reader does not want to do so much work then, in the absence of anything like an analysis by anyone else in authority, it is a useful reference.
I recommend you put together your own analysis document so you can add bits, extra notes, diagrams - well worth the effort.
Does anyone know of an analysis effort like this by anyone other than this Boeing fellow? That's why I recommended it.
