Boac, yes, well in that case, only these two:
The PFD flag at 210Z was an "airspeed limit" warning (error code 2283)
The PFD flag at 211Z was a "flight path vector" warning (error code 3412)
fell into the definite bin.
These results were passed along via an exchange of emails so I will try a prearranged phone conversation to see what else can be made more solid in the list.
