You specify 500,000 as the limit between the A and B segments, and 150,000 as the limit for the B and C segments.

All characteristic values with an key figure value of more than 500,000 are assigned to the A segment, all characteristic values with an key figure value of less than 500,000 but more than 150,000 are assigned to the B segment, and all characteristic values with an key figure value of less than 150,000 are assigned to the C segment.
