Hover a symbol for its definition. Drag a slider or type a value; the equation above updates as you go.

The bars are logarithmic. The equation is a product, so a term's effect is additive only in the log. Bar length is log₁₀ of the term and the bars sum to log₁₀ Ψ_Theater. Left of the line costs, right of it adds. Blue marks Ψ scores and green marks Γ coupling coefficients, the same colouring the suite uses throughout.

Every term has the same elasticity. In a pure product a one percent change in any term moves Ψ_Theater by one percent, whatever the term's level. The ranking under Contributions is therefore not a sensitivity ranking; it is a ranking of what each term is currently costing. The binding constraint is the term furthest below 1, and raising it to 1 alone multiplies Ψ_Theater by the reciprocal.

The presets. Both scenarios are the worked examples of Paper X, Table 7, which score the first six terms and leave the remaining nineteen at unity. They reproduce the printed Ψ_Theater of 0.158 and 0.012, a ratio of 12.5 driven entirely by the C2 coefficient.
