PSDA.Application:1.4 - Use a numerical slice at its actual scope

PSDA.5 keeps no-new-purchase baseline N, fixed pumping F, mobile pumping M and unfinished staged proposal S visible in the present pumping inquiry. S still needs a specified first intervention before its consequences can be compared. Storage and demand-management leads remain outside this narrower set. The supplied numerical slice covers only F and M, on illustrative pumping-service-loss and incremental-cost scales:

These are model values, not monetary prices, measured municipal performance or a complete public-consequence account. Baseline, staged, assistance, protection and other material branches remain outside this calculation.

PSDA.6 keeps the declared value scheme separate from a participant’s concern. PSDA.7 distinguishes an assumed road-loss probability from an established one. PSDA.8 can compare the stated consequences, and PSDA.9 exposes a possible reversal rather than hiding it.

In this deliberately stated weighted-loss model, let p be the assumed road-loss probability and λ the declared cost weight. The two totals are 2 + p + 8λ for F and 1 + 8p + 5λ for M. F is lower only when 7p > 1 + 3λ. With λ = 0.5, p = 0.2 favors M; p = 0.6 favors F. Neither probability nor the weight has been established for the board’s decision. When the missing contribution is a trade-off from expressed consequence comparisons, use PSDA.6:4.5 and its worked construction in :5.5. That deterministic value account alone does not supply preferences over uncertain outcomes.

The result therefore identifies a decision-bearing uncertainty and a conditional comparison. It does not prove that a probability obtains, that assistance is reachable, that a protected condition can be traded away, or that F or M should be bought. More decimal places would not close those gaps.
