Pac Rotors will hopefully agree that I have fully explained why the effect increases
as I have fully described it in graphical terms in my book.
I firmly beleive I have the answer and although I have never had the opportunity to Read Ray Prouty's book (one day, hopefully!)
I have come up with a similar description as
Skycop describes (I used a doughnut simile thinking I had thought of it... Bah !)
I also used the triangle of ingredients that offshoreigor has mentioned, as taught to me by Mike Green of CFS.
Give me a day to get other stuff done (like work!) and I'll see if I can convince my computer to allow me to post the graphics on the thread...!
By the way, I too am not a fan of the description "settling with power'
It's to cuddly and friendly, it does not impart the seriousness of the situation.
'Settling' is what happens to the contents of your coffee jar during transit. Vortex Ring State as a title is a little more threatening, a little more violent, and so it IS!
