Yep.
It does, and I agreed with your sentiment there. I happen to find it useful to introduce some slippery surfaces (as well as some uneven surfaces) into training, so people can experience the differences on their own, rather than having to take my word for it. You know, so they aren't relying on stories.
It is, in fact, one reason a tornado kick might not work. It wouldn't be my first thought - I just prefer simpler mechanics - and it doesn't preclude their use. In fact, if I was evaluating a tornado kick for use in the street, one thing I'd do is train it on something slippery. Again, to get some actual evidence to work with.
If you say so. It's a reasonable assertion, but one I can't support or counter, since I don't know any tornado kicks.
Actually, the "side of the argument" I've taken is that it's useful to train on variable surfaces (on purpose) to test what changes there, rather than guessing. You assumed my argument was that this would produce an entirely different approach. In fact, there are some things I'd avoid on slippery surfaces. Why? Because I find them unreliable when I practice them on slippery surfaces. Again, based on evidence.
But, as you've done several times in the past, you're trying really hard to twist my argument into something you can bash. If you stick to my actual argument, you might give me some good food for thought (as you often do). When you counter an argument I'm not even making, that's not much use.
