It seems u follow cricket somewhat. But we people always forget, before declaring anyone wrong, we should always have complete information. You must have heard this phrase - "LITTLE KNOWLEDGE IS DANGEROUS".
Now i'll tell u how. In super 8s, every team is playing 6 matcj each. This is true. But they took points from their league groups also (ie, when we had 4 groups in 1st phase). Two teams out of the 4 in each group were qualified, and the two who qualified, thier league match point are also included.
Example, In our group, SL and BAN reach stage 2. Hence, their match in league stages also is counted. So it becomes 1 match in phase 1 and 6 in phase 2 (equals to 7 for each team)....
Hope now u have a better knowledge hows the world cup is taken care off..........
