2,526 qualifying filings a year. New domestic wells across the 13 counties below, in water hard enough to be worth treating. That is the count the price is set against.
98% carry a mailable address. Measured over the 2,642 rows this seat delivered in the last 365 days — a different and larger population than the qualifying count above, because it is every row the feed handed over, not only the ones hard enough to sell into. 2,585 of them could be posted a card today; the rest carry coordinates we can drive to and no deliverable address.
Hardness resolution. 54% of delivered leads carry a hardness reading from tested wells in their own ~7-mile grid square; 39% carry their county's median instead and 7% carry no hardness reading at all, because fewer than three wells nearby have ever been tested. Measured over 2,616 rows.
Three measurements over three different populations, each named above. They are not multipliable against one another and none of them is a forecast — every one is a count of rows this territory has already produced.

Every row carries the property, the measured hardness at that property, the county, the filing date and the driller. See a real doorstep report — the sheet a dealer leaves at the door — and how every figure is derived.
