A rotor disc is a rotor disc - I taught this manouver for years to all students in the R22 and 47.
Using the rule of thumb of 400 ft for every 90 degrees of turn in the R22, the question was raised how do you land in an area that is just passing under the machine when at 800 ft AGl above 53 kts and the engine quits.
Enter normal engine off configuration and keep the Cyclic coming back smoothly. Trading Fwd energy for Altitude, the machine will not loose too much altitute and MRRPM will stabilise within limits.
You will feel transition go and then return as the disc takes the machine backwards. The nose will pitch down when this occurs.
At this point you will see the touchdown spot and can judge how long to hold the "rearwards flight attitude."
Then - cyclic forward - thru transition, nose down quickly and smoothly down (quite a bit) to gain above the flare gate speed of 53 kts, cylic smoothly aft and hold the IAS above 53, flare and land. Simple.
Similar deal in 47.
I never use cyclic in the flare before touch down as I consider it to be a "Hand Brake" on the Rotor energy.
Think about the advantages of this if you have to drop into a vertical hole in the bush from 50 ft AGL .
