^ Nah, I do get your point. In theory, I actually agree with you. It's just that I've often heard that the timing is off which can actually be confusing to some beginners trying to make the transition. Maybe they've improved that. I don't know.
Besides, there's so many other ways, especially with all of today's technologies and networking offerings, that I just think it's more of a hinderance than an enhancement. Then again, if it gets one practicing compared to traditional methods, than c'est la vie.
