If this is not already in the Robinson safety course - it should be.
I think it will be - I have attended the RHC safety course where Tim Tucker showed all sorts of R22/R44 accident videos from all over the world - except the USA itself. Either our American friends never make mistakes, or else he has done this deliberately for US marketing purposes.
Is LTE recovery (by the book) any different from LTR recovery?
I think the POH says autorotation (I haven't got it with me) because that's the easiest option out. The skilled pilot would however roll off throttle, lower collective and once the spinning slows or stops, forward cyclic to pick up airspeed, assuming sufficient height in the first place.
