Don Shirley (extended)
Combined power Jul 22, 1961 → Jan 6, 1962 · 18 weeks
Solo career plus "Don Shirley Trio", billed under the leader's name; MusicBrainz lists it as its own act, so it is grouped rather than merged (credit survey, 2026-09-24).
billboard-hot-100 and uk-singles combined, weighted · How it works
Each week an artist's share is the weighted mean of their Power Share across billboard-hot-100 ×1 and uk-singles ×0.45 (weights ∝ √population, US = 1). The divisor is every chart's weight, so a number one is worth the same share in any era — and a week before every chart exists, or after one's data ends, sums to less than 100.

- weeks with chart power
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.
| Member | Weight | Contributed power | Weeks |
|---|---|---|---|
| Don Shirley | × 1 | 0 | 1 |
| Don Shirley Trio | × 1 | 5 | 17 |
Contributed power = weight × the member's own Power Share, summed over weeks. The member's standalone page is unaffected by this grouping.
