Are you doing these with an instructor? (I hope).
If yes, find another instructor !!!
If no, find an instructor !!!
From your description of the maneuver, it doesn't seem you or your school has a "procedure" for demonstrating this.
For my students I use:
Establish Hover at an altitide that will ensure recovery by 1500ft AGL (read: Plenty high)
Slightly lower collective to achieve ~500fpm descent
When buffeting starts (or other such excitment) increase collective to show it will not arrest rate of descent
Pitch over to regain airspeed (remove one of the three conditions of VRS)
Establish Vy climb
And, this is what the Examiner in our area wants to see on check rides.
Fly Safe.
