Catalog albums maintain UK chart status through continuous streaming velocity and weekly retention dynamics. Adjusting the weekly retention slider alters the effective velocity, extending projected total chart weeks and milestone dates. Higher retention elevates the decay horizon past 900 weeks, advancing the album into top catalog endurance percentiles.
