Until the point at which you try to gain airspeed or get close to the ground. 20' above the ground is not the time to find out either that the wind isn't going to help you or the fenestron blade pitch isn't enough.
In this totally hypothetical scenario, I think I would prefer hitting the ground (even whilst rotating) from 20' rather than climbing back up and hitting the ground from much, much higher?
All totally hypothetical, not even remotely in line with the evidence, and frankly a little crazy!
