Ramsey Lewis (extended)
Combined power Oct 10, 1964 → Feb 14, 1976 · 134 weeks
Solo career plus "Ramsey Lewis 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 |
|---|---|---|---|
| Ramsey Lewis | × 1 | 21 | 83 |
| Ramsey Lewis Trio | × 1 | 36 | 51 |
Contributed power = weight × the member's own Power Share, summed over weeks. The member's standalone page is unaffected by this grouping.
