Having experienced this in “fright” in a medium twin and light helicopter operationally plus instructing and looking for it this is exactly what I found effective. An ample amount of forward cyclic to give positive accelerative attitude (at least 10deg nose down) with a slight decrease on collective works instantly in IVRS, I would be surprised if any less so than Vuichard. It also recovers to forward flight with no further input and the better side of the power required curve.
As you have stated any later than the early stages of IVRS is likely to to ineffective for both techniques and require more height to recover than it’s likely to have.
