If you read back a few hundred posts or so, there was already fairly clear evidence and discussion about the direction and forces required to break it off...
I am now (trying) to go one stage further, the subtlety of bringing it back into discussion after BEAs preliminary comments though, seems to keep getting lost....
I think I see what you are driving at: As with the vs, there does seem to be disagreement between the report and direction of travel required to sever the vs and / or spoiler, unless the impact vectors included speed opposite to direction of flight. Correct me if i'm misreading this, or you have a better explanation.
As an aside, some info and pics on spoiler manufacture which may be of interest:
