Waiting for the FDR

I have been wondering about the altimeter setting. The transcript indicates 745 which is likely a QFE.

Was this a good setting: what QFE did the press plane use?

Was the QFE properly set onboard?

But then there's the descent rate as the CVR raises the possibility of a duck under during the last 100m, we are hearing the Navigator announcing 10m lower about every half second. There's 6.5 seconds between the Navigator's 100m and 20m announcements -- a descent rate of approx 740m/min or 2400'/min.

10:40:48,7 - 10:40:49,4 Nav: 100.

10:40:55,2 - 10:40:56,0 Nav: 20.
Of course if he's reading the RA, a good chunk of that descent rate would be the ground coming up -- the FDR will tell a fuller story.
