It just gives you an increased level of protection on the usual stormy days in the UK where winds gust to 30 or 40
Realistically it gives you virtually no protection with anything that a normal pilot can move.
The 700 pounds per tie down is over 300kg per point so your going to strap a ton to your aircraft before its going to do any good. The volume of concrete alone is going to make it interesting getting the aircraft to the tiedowns.
All that Sub 100kg for a tie down is going to do is fatigue your structral load point as it jerks it. It will only make 1-3 knts difference in the wind speed thats required to cause the aircraft to go flying by itself.
The only thing that really works is perm inverted mushrooms installed under apron concrete and once you have them all you do is transfer the failure point from the tether to the bit of rope that you have used to attach the plane to them.
