The FDR file in the public docket only contains Control Column Left (Pitch Control), Elev L and Elev R. All values in Degrees, no forces. So roughly assume Ctrl Left=Ctrl Right before the split, after that you need to guess from the ELEV R what the First Officer did. I was close to provide a higher resolution Graph of the final seconds, but it's difficult.
It also seems to say in the report that the Captain accidentally pressed the TOGA switch. How is it known who pressed the switch?
I remember from the hearing the most probable scenario was the F/O guarding the SPD BRK Lever as per procedure, bringing his hand+wrist close to one of the TOGA switches. Then 5-1 seconds before G/A mode those light turbulences affected the aircraft. Means they don't really "know". It's very likely to be related to the "turbulence", it's not known who touched it.
