It's further complicated because A320 simulators are not the same. Airbus changed the ground reaction model from IIRC standard 1.8 and this certainly made is very significant difference to the handling qualities during this phase. Additionally a major Canadian TDM doesn't use the Airbus data but their own Ground Reaction model.
A good acceptance pilot advising engineering can usually compensate somewhat for these idiosyncrasies but the fact that very few A320 simulators will react correctly to a hard touchdown shows how poor the ground handling models are.
