Greatest Test bowling performances                                                                                                        

The following factors are considered to rate Test bowling performances.

1.  Bowling Base Points
The bowling base points are given for wickets taken.

2.  Bowling Accuracy Index
This index reflects the accuracy of bowling. The runs given away by the bowler is compared to the opposing team's total score.

3.  Pitch Index
This index is determined based on the runs scored in the match. Normalizing is done to take care of wide variations.

4.  Dismissed Batsman Quality Index
This is an important index, which distinguishes between two bowlers who have taken 5 wickets each, the first one, batsmen 1-5 and the second one, batsmen 6-10.

5.  Highest Wickets Index
This is a low rated parameter, and is given to the analysis if the same is the highest for the team.

6.  Home/Away
This is another low rated parameter with points awarded if the innings was played away from home.

7.  Match Status Index
This is a complex index, which reflects the status of the match. The highest value is given to a successful, close fourth innings defense (de Villiers' 6-43).

8.  Result Index
This index is based on the player's contribution to the match result. The match should be a win or a draw for points to be allocated.

9.  Milestones Index
This is the lowest rated parameter, with small bonuses awarded if the wickets taken in the innings is over 6 or 8.

In addition, the ratings calculated is downsized proportionately if the wickets taken are less than 5.
