True enough, but I wouldn't like to stall a DA40 into the ground. Firstly, there's no give in their seats, whereas the SR20/22 have aluminium honeycombs under theirs, to absorb the energy from a vertical impact. Secondly, the DA40 would still be moving forward at a fair lick, so that energy would have to be dissipated as well. This assumes that you could still control the aircraft, which is not a requirement when deploying the parachute.
