DEDUCTIONS AND EXISTING STOCK

Tapered pot fill around root balls — root-ball displacement per pot scenarios.

How does changing root-ball displacement per pot affect tapered pot fill around root balls when the other inputs stay fixed?

What this decision changes

A known internal space, existing stock or shared quantity must enter the correct subtraction or eligibility step rather than being counted as new material. Method basis: Pot fill = π × fill height × (top radius² + top radius × bottom radius + bottom radius²)/3; subtract supplied root-ball volume.

The focus is supplied root-ball displacement per pot in the first repeated measured entry. Other repeated entries keep their own supplied values.

Keep the comparison within scope

The supplied cavity, exclusion or stock eligibility must already be valid; the result does not select a safe shell, opening or construction detail.

Does not choose installation schedules, safe system properties or regulatory compliance.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
