this link refers to the alleged video (article not video) which is accompanied by the timeline from BEA.
10.30 captain has left flight deck, lock is operated?
10.33 captain heard telling FO it was him trying to enter
10.40 right wing clips the mountain.
that is a minimum of 7 minutes, CEO GW confirmed their reset period is 5m (can be 5-20m).
Think it is fairly safe to assume he had tried the code 1st, didn't spend long in toilet again fairly safe to assume he recognised they were in descent.
