Charting Feb 18, 1978 → Dec 10, 1983 · 21 weeks with chart power
Charted in 1 of 2 markets · top artist of the week in it — UK Singles Chart 21 wk (2 at #1)
Billboard Hot 100 and UK Singles Chart 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 Chart ×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 sums to less than 100.
