Evidence grade

Reference scale, grade Derived. Not a forecast for your business. This figure describes what a decision of this shape has been worth at this scale of operation, drawn from the evidence named in section 02. No payback, return or year-one figure appears in this brief — no fee has been quoted, so those numbers cannot exist yet. They are computed against a signed quote and stated with the fee beside them.

The decision this model makes

A studio appointment ends with a signed selections sheet and everyone moves on. Nobody sets that sheet beside the one signed on the same plan, in the same community, by a different consultant last week.

Consultants get compared on total dollars written, which rewards whoever was handed the move-up product.

The options ledger already carries the consultant on every line. Joined to contracts it gives attach rate and dollars per contract per consultant, held against plan and price point so a consultant working the entry product is not scored against one working move-up.

What is left after that control is coachable: which categories a consultant never opens, which ones they open and lose, and which appointments convert at half the rate of the rest.
