So PRIM2, which is missing on set of ADR data
completely (according to this interpretation of ACARS messages), doesn't care about the missing data and computes with only 2 sets as if there had been always only 2 available and never 3? I'd rather expect that, given the importance of the these data, PRIM2 would be less likely to return to NORMAL.
