In low air we do the revolutions from above, it covers the ball from front wiew, this counts as a revolution.
In sitts we do the revolutions from below because our knee is under the ball.
If u get around the ball, with your foot or sole, is also counts.
it is basicly a knee cross-alatw nt but these two tricks are very related so I think it can be considered as one trick. As I know, I did it first in the world, that's why I named it Kvartam trick.
thanks for the posisitve comments
