Going back to your original post - you were referring to SWP which, as we have discussed at length, is not IVRS or VRS.
So, consider your circumstances - you were trying to hover OGE with clearly limited power available (up at the red line you said) so how does the Vuichard technique get you out of that?
The amount of collective you have available is minimal (red line) and applying full power pedal just saps more power. All sideslipping to the right achieves is getting translational lift to the MR which you could get by just moving the cyclic forward instead.
Then, when the vertical component of your Total Rotor Thrust is the only thing opposing your weight, you tilt it, thus reducing the vertical component even further.
I'm really not sure how this is supposed to help!
All the stuff about reaching the upwind side of the vortex is more bollocks because you aren't in VRS, you have just run out of power.
The BIG problem is that many less experienced pilots reading this forum will think there is a magic bullet recovery for IVRS or VRS when the only guaranteed way is to avoid it altogether.
If you want a proper top tip then only approach a hover OGE level rather than descending to it - when you are limited on power it is much easier to assess your real power demand as you approach the hover as you are not trying to arrest RoD and forward speed. As you start to reach your power limit then ease the cyclic forward and fly away if you have any concerns.
