I use this technique for chipping and it really has helped me around the greens. One additional thing that significantly helped me with this method, and I did not see it mentioned here, but I see that Eric does this instinctually in his video - for me, its absolutely essential to focus on the spot of the ball, even after impact. I always wanted to look up right at impact, and this dramatically reduced my success with this technique. I still really have to be diligent with this - as my inclination is to always look up too early in the shot. Hope this helps someone else...
