A daily leak prices differently than an occasional one.

Four numbers, multiplied

Factor	Where it comes from
New-patient inquiries per week	Your answer — midpoint of the range you pick
× estimated peak-miss rate	Conservative lookup keyed to your Peak-Hour Score — more flood hours and slower recovery push it up
× close rate for your practice type	Conservative working assumption, stated in the report
× value of one patient relationship	Your answer

A clinic with 28 inquiries a week, a score in the "Leaking" band (28% peak-miss rate), a 25% close rate and a $2,500 average patient: 28 × 4.3 × 28% × 25% × $2,500 ≈ $21,000 a month drowning in two predictable windows a day. Predictable is the operative word — this is the rare leak whose location and schedule you already know.

Estimates from your own answers using stated assumptions — labeled that way in every report. The $500 discovery replaces the estimate with a measurement.

The staff cost the spreadsheet misses

The flood also spends your people: the desk's best employee ends every day having lost races they were never given tools to win, apologizing to the counter AND the phone. Peak-hour churn at the front desk is expensive and demoralizing — and much of it traces to structurally impossible noons. Covering the flood is a retention play as much as a revenue one.
