Ten indicators are taken into account for the cumulative results. If at least eight scores are significantly better than average, this is seen as a combination of favourable scores.

The reason for the difference in thresholds is that there are more positive scores on average than negative ones. By using these thresholds, the group at the bottom of the distribution is about the same size as the group at the top.
