If that happened, how did the Captain not say or respond the first time, or did he?
Detailed in the report, but Capt was not on Flt Deck.
In fact, the descent was ATC instructed and flown normally, the "practice" was just the selection of 100' (and other incorrect values) on the FCU for periods of time as I read it.
Not much new I saw in the Prelim Report, but a useful summary of the current factual status.
