Field notes
Headway groups past applications to estimate the share of similar projects built by each year after applying, while accounting for projects that remain under observation. The page names its data sources and says estimates use resampling; it also limits coverage to applications predating the 2023 rule change, so newer projects cannot yet be scored.
