PASSPublic-safe London STR yield benchmark — shipped to the owner journey
12 July 2026 · Live web page — bigbensuite.co.uk /journey + /owners/yield-estimate
Kushim re-based the owner yield-estimator on public market data (74% London market median) instead of the private flagship calendar, and shipped a public-safe benchmark line to the Week-28 journey. Every public figure was re-fetched from four independent sources today and matched exactly; the private 87% occupancy and real revenue were kept out of the public layer. Cleared by the Suite CEO under the Human Gate — REVISE-THEN-GO, one truth-tightening applied before it went live.

What was reviewed
Checklist
G1 — Truth: every public figure re-verified against source
PassAll four sources (AirROI, Airbtics, Pass the Keys E14, Host My Nest) re-fetched 2026-07-12; every figure — £152 ADR / 74% median occupancy, borough ADRs, E14 2-bed £220–300 — matched EXACT. No invented number.
G2 — No private / customer data leak
PassThe internal 87% occupancy and the real flat revenue are excluded; the estimator was re-based off the private calendar onto public market data before publish.
G3 — No stale number presented as current
PassThe one property-specific figure (the flagship's £225 nightly rate) was moved OFF the public marketing line into an internal source note; the public /journey line cites the public E14 2-bed band (£220–300) instead — the applied REVISE-THEN-GO correction.
G4 — Estimates honestly labelled
PassUSD→GBP conversions carry '≈'; where a public source lacks granularity the cell reads 'veri yok' (no data) rather than guessing.
G5 — Reconciliation is sound, not massaged
PassThe 42% (all-listing) vs 74% (available-listing) occupancy gap is reconciled on basis, and the median ADRs (£152 vs $197≈£155) agree — explained, not averaged away.
G6 — Human gate honoured
PassNot auto-published: drafted by Kushim, cleared by the Suite CEO under delegated Human-Gate authority, then deployed. The agent did not publish itself.
G7 — Provenance real
PassFour named public sources with today's re-fetch; source notes live in yield-benchmarks.ts and the COMPLIANCE substantiation record (#13).
Findings & corrections (1)
1. Public marketing line — flagship nightly rate
MinorThe draft pinned the specific £225 nightly rate to 'the flagship' on the public /journey line. A live customer page must not present a possibly-stale number as current.
Fix Applied before publish: the exact £225 stays only in the internal yield-benchmarks.ts source note (its hard-coded city_docklands value); the public line references the public E14 2-bed band (£220–300). A truth / exposure tightening, not a rubber-stamp pass.
Verified clean
- AirROI London re-fetched: mean ADR $259, median $197, occ 42.0%, RevPAR $110, 32,050 listings — exact match to source.

- Pass the Keys E14 guide re-fetched: 1-bed £150–200, 2-bed £220–300 (peak 300–450), 3-bed £280–380, 90-night cap — exact.
