Helonorth - next time you do it - same conditions of entry you were using on these training course - just add full power and see what happens.
You will almost certainly recover as quick if not quicker than with the Vuichard technique.
Why? Because you are in the very early stages of VRS (you recognised it early because you put yourself into it) and pretty much any recovery technique will work.
The only reason you compare it to the 'standard' recovery so unfavourably is because the 'standard' technique is the ONLY one that works in fully developed VRS and therefore it was taught for any VRS conditions.
Guess what? If you lower the lever and push the nose forward, the RoD increases and you lose a lot of height compared to raising the lever and cross-controlling.
But also guess what? If you are in full VRS, the 'standard' technique is the only one that is going to save you.
Now if you think this 'new' training will help if, heaven forbid, you do actually enter full VRS then you are going to be sadly disappointed.
Go and try your 'new' technique but hold the shudder until the VSI starts to point hard down and see how good it is. - In fact don't do that as you will probably crash.
Light helicopters with lower disc loadings are more susceptible to VRS as their downwash speed is lower and it takes less RoD to catch it up and ingest it.
All Vuichard is doing is selling early recognition - something that has always been taught - and added a twist to make it look and sound sexy.
