"Demonstrated Crosswind Velocity is the velocity of the cross-wind component for which adequate control of the airplane during takeoff and landing was actually demonstrated during certification tests
Here we are dealing with fact. Something that has been demonstrated, has been checked and which has been certified and something that the average pilot can repeat on a consistent basis.
The value shown is not considered to be limiting
That is opinion or speculation and is not based on any calculation demonstration or result.
What is says it that adequate control exists at the max demonstrated crosswind. It may or it may not exist above that figure.....if you want to try and find out, don't blame us if the aircraft breaks or you hurt yourself.
Your insurance company will expect you to take reasonable care. Test flying is prohibited by most policies.
