Weekly monitoring index (52-week transforms). Buys timeliness and turning-point speed, not calm-period precision; prone to false signals and to base-effect echoes a year after large shocks.
Staggered combination of an official-data block, a survey/indicator bridge and an autoregressive benchmark, re-weighted through the data release cycle. Backtests are walk-forward against the latest vintage; pandemic-window observations are excluded from estimation and shown separately. Sources: ONS, Bank of England, public high-frequency data.
