Ref p9 of the FDR plots. There seems to be a disparity in recorded TLA when you would expect them to be on the idle stop (0° on 1 vs. ~-3° on 2) during flare and at the end of the landing roll. This is the previous landing at Porto Alegre where the PF apparently used the latest SOP with Rev Max on both i.e. no stagger expected at any time.
