Have a look at the record.
Cirrus Airframe Parachute System (CAPS) Deployment History - Cirrus Owners and Pilots Association
It challenges some of your assumption and just about all of Mr Guppies.
My friend had over 10,000 hours, a good mix of CAT and GA. She landed her Pitts in field - and it looked a very good field indeed. The aircraft hit a rock, flipped and she spent six months in hospital. With respect tell her she was not a good pilot - not many are better.
As to your last paragraph you make a valid point. However if you read my earlier post you address the point I sort to make. Objects may help to disipate the energy but equally might fail to do so. Toying with hard objects is not predictable.
Mr Guppy
Have a look at the COPA web site (see above). The whole of your post is ill informed and has little or no basis in fact.
You are well advised to avoid getting to close to anything factual.
