There's no point in such work (other than for ego) because it can't possibly describe what occurred without the flight data from the recorders. Anything else is just a cartoon.
Sooeet nailed the Asiana 214 final approach profile days before the NTSB released several data points of FDR data for the last 3 nm of the approach. What makes you think that a similar analysis for UPS 1354 is any less accurate? Aren't you jumping to conclusions before looking at the data?
