Because you talked about it being a larger or smaller 'envelope' for avoidance of VRS - implying that the larger your 'envelope' the easier it is to get into VRS.
That is completely wrong and I would hate less experienced pilots to think that if you have a 'small envelope' in a lighter helo that you are safer and further away from VRS when it is exactly the opposite.
I think you should read what you have written and look back across the plethora of threads on pprune about VRS.
Don't talk about 'envelopes', it is counter-intuitive and utterly useless in the real world.
I have put some practical suggestions as to how to avoid VRS in my previous posts based on real-world situations and experience.
The only issues I have are with pilots not understanding how VRS can be encountered.
