The multiplier model
We model your current response time as a multiplier anchored to the 60-minute baseline. The under-2-minute bucket carries a 4.91x multiplier, derived from published conversion curve data.
What moves the grade
The grade reflects your response bucket: A (under 2 min), B (2-5 min), C (5-15 min), D (15-60 min), F (over 60 min). Most businesses we audit start at D or F.
