It's not due to rounding error. It's due to the match schedule.

If you look carefully, you'll see that the average CCWM is zero only for those events where the schedule had each team playing the same number of times.

When you do World CCWM, this effect is exaggerated.

The CCWM residuals, however, will always sum to zero, regardless of schedule.
