Interesting. I'll have to play with the concept at the gym today.Not fully caught up, so this may have been addressed. But in my kempo, we learned some Fu Jow Pai (I think actually hung ga, since I never got advanced in that aspect), which included a 't stance'. My understanding of it/what was explained to me, is that there are times you lose balance, and that is a good 'recovery' transition stance for when that occurs. It's not a stance you want to be in, but if you train it, you can quickly get back to a safer stance.
