I *think* it takes the throttle position, what the a/t wants and what the fadec sees.
With 1400 data points I wouldn't be too surprised if the FDC has a parameter to tell if the pilot had the ham and cheese or roast beef on rye for lunch.
Should cycles be a metric pilots track along with hours to measure experience?
ETA: My guess would be the Asiana bird did not have WAAS
