Adjusting RPB in your game

Hi Nikhil,

Well done.   You are part of the way to developing your RPB.  This is a path that everyone learning a skill takes.  FIrst you will struggle with the technique.  Then you will learn the technique and be bale to play it in a controlled situation where the ball is fed to you.  Then you may be able to use it in a practice match situation.  Then you will progress to being able to use it is a real match situation.  FInally you will progress to a level where you will feel confident to use it in a close situation in an important match.

As you can see you are part way there.  You have done a lot of the hard work, now it is getting more experience with it and progressing through the stages of learning.
