How the model works
Response-time impact curve
— NOW marks your current position.  — TARGET marks your improved position. Steeper sections of the curve mean greater uplift per hour gained. Coloured bands show the speed rating zones.

Evidence basis The uplift thresholds reflect empirically observed step-changes in B2B conversion rates at key response-time boundaries. Harvard Business Review (Oldroyd et al., "The Short Life of Online Sales Leads", 2011) — analysis of 1.25 million sales leads found businesses responding within one hour were 7× more likely to qualify a lead than those responding an hour later. InsideSales.com / XANT Lead Response Study — contact probability drops by over 80% after just five minutes. Buyer Revolution / Demand Gen Report — B2B buyers now expect a substantive response within 3 hours of initial enquiry; the majority choose the first vendor who responds. The threshold bonuses in this model are conservative proxies for those published step-changes.
This estimate is based on your inputs and a response-speed weighting model. ROI is calculated using revenue uplift against system cost and is intended as a directional estimate.
