Agreed. I know from my writing of RCA reports when things go wrong (but thankfully not accident reports), that it is important to mention what data has been considered & dismissed (and why), exactly in order to avoid people spotting things that I did see in the data but were not causal and hence not addressed by a "fix", but they would otherwise
think I didn't see them...
I'm sure the BEA have people with much more skill & practice in this area than me, which is why their omission is odd, and leaves open multiple interpretations - from "there wasn't enough time in this interim report to mention it, but of course we saw it, and it wasn't important here", through to "oops, we didn't notice that", and everything in between.
