I'm not convinced by the 26th bit error theory. If you look at the AoA data from the previous flight in Fig 7 on page 16 of the preliminary report, the AoA disagreement is there from the start, but it increases significantly around rotation. This isn't really consistent with it being a constant 22 degree error.
