Recheck your spoiler response....What the pilot considered, created their collective reality. That you do not understand this is what keeps us miles apart.
What the CVR has in the way of usefulness is lost on you when you use it only to qualify a mechanical log... It is the human version of the DFDR.
I can't discard your take on the CVR contents, but it is half full.... Their is more to spoiler operation than roll, and drag, likewise deficiencies in position sensing that you do not consider. Position of spoilers can be correctly displayed without the spoiler being attached to the actuator. For example only, not a statement of support for any theory...
