MS;
I think it is very important to disagree with any and all presented information until we know it is from the primary source and the primary documents, (the Airbus 330 TSM, MMEL, etc) or has been established as irrefutable. The ACARS documents are good but we dont' have the originals.
I think it is wise to reserve judgement on an "expert's" interpretation and prefer a "college of experts" such as reside here, all disagreeing until "what is" is no longer disputable. I think because of the circumstances, any evidence must meet particularly high standards and theories/conclusions wholly avoided. Hind-sight bias is still an operating factor.
