Won't be differing with any of that!
Will only add that recovery method has to be 'tailored' to height available. At 3000'
that's one thing, at 75' into a confined is something else. Poor speed/power management is the major cause but a downdraft would be very unfortunate at the latter height.
I stick firmly to the 30/30 rule, no more than 30(0) ft per minute if speed is less than 30 kt. You won't fall into any trap then. I have also heard that it cannot develop at approach angles of LESS than 30 degrees but have had no time to go into that.
Maybe someone else has?
