For just this reason why the original Bristow system was slightly more complex in that it both catered for a modicum of energy dissipation but more importantly it conducted continued monitoring of the 'sensors' and would cater for the eventuality that the sensors were 'disconnected' during an incident.
If I remember correctly Sikorsky only tested the S76 ability to handle float deployment to a factor above proposed arming speed, can't recall the figure but hence the FM limitation
