well..everytime i played tennis elbow, only today i knew this rule!!!
And i think many people here don't know that rule too
so i think this topic is good to remind everyone and if you don't know what is it, you can ask here...
But talking about it...man is totally different, i always played with 0 points, all with 100% exept topspin... and when i changed...oh man..the results!!
i hope this can help many people...this helped me and i think today my results will come better.
