So wonderful that you finally have something tangible, defined to take action on! And a result that explains so much that was at odds with previous findings.
I too find that even with all that access to sound and great comprehension it doesn't really mean our wee ones will listen in the behavioral sense 
. This morning I patiently (well, maybe the first 2 times, then a little more insistently ) made a request 4 times over to no reaction, and thought, are her processors off, batteries wonky, is something wrong? And when I tapped her to get her attention and sign my request, she stopped me at the start and said "Mama, I know, I heard you 4 times, but I'm too busy reading." When did she go from 4 to 14 years old?
