Well, according to Polish media, they all say that the 3rd recorder registers "podwyższone" flight parameters. The problem is "podwyższone" doesn't seem to be a technical term but rather some sort of miss-translated Russian/technical jargon. The word "podwyższone" literally stands for "elevated", but it may also mean improved/refined/extended/advanced... Maybe that will point you in the right direction.
I believe it's for "exceeded", so it fits QAR definition.
