| Signal137 | What changed because of this event, net of what would have happened anyway? | Gross activity through counterfactual, displacement, and leakage to attributable retained value | The legacy figure survives the auditor's first question |
| Signal137 | What does the visitor economy support, and where does the value stay? | GVA, employment, and tax with a segment-level supply-chain and retention breakdown | Procurement and licensing targeted where retention is weakest |
| Signal137 | What did the public intervention return, in the same terms as its cost? | Fiscal return and wider public outcomes, stated separately, with the counterfactual | The return audited the way the cost is |
| Signal137 | What did visitors do and feel? | Zone and segment-level behaviour and sentiment, aggregated before any analyst sees it | A pattern the board can act on, not a profile of any one visitor |
| Signal137 | What did the activity emit? | Emissions by category, each labelled measured, modelled, or estimated | The carbon claim defended with the same discipline as the economic one |
| Signal137 | Which events in the calendar are delivering, and which are not? | Every event ranked on jobs, tax, GVA, and retained value, on one method | The productive events supported; the mix optimised |
| Signal137 | Can I have the answer today, not at the end of the quarter? | Reports on demand: any route, event, or season, in minutes | Evidence arrives while the decision is still open |
| Signal137 | Can it produce a negative or neutral result? | Yes, and it should | A tool that only finds positive impact is not credible to a treasury reviewer |
| Signal137 | Do we need a live data connection? | No. Data refreshed on each source's documented schedule, access agreed before a project starts | Nothing claims real-time access by default |
| Signal137 | Who holds this, and where? | Model, data, and a trained team inside your jurisdiction | The capability survives the change of official or consultant |
