Apologies for my lack of patience earlier.
As others have explained, it's not about the whizz wheel - it's about developing the understand of the triangle of velocities problem that you have to have in order to use the whizz wheel. Learning to use it is itself a test if you will.
Have a search for ' mental dead reckoning'. That's what you need really to be able to do. It is the gross error check that you need using any type of calculator, it's what you will need in real life if your iPad goes down to avoid having to make @TopCat 's Pan call, and actually it's all you ever need to flight plan in the first place.
But it's not enough to pass the exams - so there I suppose I do agree with you....
