SDK 2.0.8 reliability and accuracy

Would be interested in hearing from anyone that is having success with the new skeletal tracker. We have been testing the new 2.0.8 sdk for some time - but are finding that the accuracy of the tracking is very poor and far from consistent.

Moving your right hand from RIGHT to LEFT across the viewport seems unable to track an even remotely smooth path with the depth and y axis moving around noticeably the closer you get to the body - and then seems to fall apart completely the further across the body you move - eventually becoming very confused is its a right or left hand.

Is anyone seeing better results ?
