Did you read §1.16.4.1 of the 3rd interim report?
Also remind that:
- recorded speed are from pitots/ADR 1 & 3
- AP2 was ON, it uses IIRC pitot/ADR 2 as primary

Wouldn't a 'bus pilot suspect some sort of FBW computer(s) malfunction and start "aviating" ?
I don't quite understant your question.

See above ; I agree with you if you replace "displayed speeds" (there was 3 of them) by "recorded speeds" (only 2).

BEA tries what? It's written plain & simple:
The table below lists the messages generated during the event, in order of priority and in a form similar to that in which it was displayed to the crew.
The
purpose of this table is to show which message(s) will be directly seen by the crew, as the screen cannot contain them all.
That's why on the next page, with the hypothesis that no message was ever acknowledged/erased, the BEA shows simulated printscreens on a
chronological basis (other purpose).
