This system has lots of flaws, for e.g. Chanderpaul was playing when the new ball was a lot & he has negative points, worse Chris Gayle scored just 2 runs and he has better points than chanderpaul. Proper weightage needs to be given. Also, some matches will be played in a bowler friendly pitch, where scoring 50 of 100 balls would be a match winning performance, but I believe this system will deduct points.
