The assumption doing the work: a lead answered within 5 minutes closes at your full rate. We assume that rate decays with delay: about 55% of it at 5 to 30 minutes, 35% at 30 minutes to 2 hours, 20% at 2 to 24 hours and 10% beyond that. Those factors are our working assumptions, not a measured benchmark, and your own data will differ. Leads never contacted convert at zero. It does not model lead quality, seasonality or follow-up after first reply. If your close rate on fast replies is under 5%, fix the offer first.
