I think it is very hard to be accurate with this conversation. Firstly, it was hardly "discourse". I think also it was not CRM. If the CVR releases are complete, I would be astonished. I believe much is witheld, and, again, the translation is questionable.
If memory serves, Bonin mentions only "speed". Crazy or otherwise, crazy is not cockpitspeak for any condition I am aware of. PNF is closer to the ideal, but it is not fair to make any finding: conversation.
Entirely lacking context and continuity, until the final is in, this banter is confusing at best!
May your beacon find a direction, bear.
