I must admit I was surprised at the deck angle on touchdown of the E190. Pretty high!
If the nose is already at 5° on final, only another 2° for a FOQA soft alert seems way too harsh to me. The nose could quite happily waffle +/- 3°-4° without causing any significant change to the flight path (and hence Rate of Descent) but in this case would cause the FOQA to go berserk.
ITCZ, You may not advocate looking in the rearvision mirror, but the fact of the matter is the FOQA reports/trigger points have a direct effect on how crews fly the aeroplane. Why would one not try to avoid a FOQA event, knowing that it will be registered (albeit [perhaps] not attributed to me)? It is not natural to do something that you know is going to be registered.
These situations are helpful because they put pressure on the boffins who set the FOQA parameters to adjust them, like Pitch Attitude High on Rotation!
