From what we were told, this procedure is becoming an industry standard as it reduces engine wear. Perhaps this could explain the strange reverser deployment in this incident.
The N1 plot is kinda hard to read with accuracy, but it looks like the N1 was at 82%, or maximum reverse when the TRs were deployed.
