Project a Weekly Growth-Target Schedule

A pure function that, given a starting metric value, a weekly growth rate, and a number of weeks, returns the compounded target for each week and the final value, mirroring the YC forward-looking growth graph practice.

You receive: A deterministic calculator (pure function) graded on hidden numeric input/output cases.

Part of Choose Business Model

What's verified: STUD verifies the compounding projection and final-value math on hidden cases. It does NOT decide whether 7%/week is the right target for this company, whether the metric chosen is a real growth metric vs a vanity metric, or whether the targets are achievable. It produces the target curve implied by the inputs, not a forecast of actual results.
