Learning happens per doubling of output, not per day. The first hundred pieces buy more than the next thousand.
— no.
Where the curve crosses the target SMV
A Wright curve has no floor — extended far enough it predicts times below anything physically achievable, so it only holds up to the operator's plateau. Learning rate is operation-specific and is destroyed by style changes: every new style restarts a partial curve, which is what makes short runs expensive.
