The a/c stalled when AoA exceeded 10° at 2h10m57s. At that time the F/O was seeing IAS from ADR3 which was still UAS, while the Captain PFD was on ADR1 which had returned to normal some 20s earlier and was showing 207 kCAS at 2h10m58s.
Without re-reading Interim #3, I believe it settled in somewhere around what would have been equivalent to 150KIAS
That's not in Interim #3, but is probably based on a graph I posted some time ago that showed CAS calculated from the recorded groundspeed.
