Exponentially smoothed share of the week's total power (the primary metric). The bold line is the group; the others are each member's weighted contribution.

| Joan Jett & the Blackhearts | × 1 | 24 | 37 |
Contributed power = weight × the member's own Power Share, summed over weeks. The member's standalone page is unaffected by this grouping.
