Rafa and his camp has denied to the press that Oscar helped his serve. Yesterday 11/3/11 in Spain Nadal was asked about the video and the lesson, he said the only thing Oscar did was to waste his time for 1/2 hr.
I think it's pretty clear that Ralph incorporated some of what was on the video into his serve. Whether it helped much is debatable. But, it's also pretty clear to me that this coach doesn't fully understand the serve, or, how to throw a ball. As a result, he was focusing on symptoms rather than the disease.
IMO, alhtough Ralph does get a good shoulder turn in his windup, the missing element in Ralph's serve is that he doesn't get a sufficient shoulder tilt and spine angle to rotate his upper body around. As a result, his serve is mostly an arm swing with little support from upper body rotation. The focus on Ralphs arm position in the trophy pose without understanding that it was being caused by having level shoulders in the trophy position (aka: Jimmy Connors syndrome), is why the lesson wasn't particularly valuable as far as I'm concerned.
