Per slot you enter an offer uplift. The model predicts the new PR using the segment's elasticity (tunable per segment), reduces margin/APC by the uplift amount, and shows Δ APCs and Δ profit. The honest question: does the volume gain cover the margin compression?
Model:
Margin segments (Parts / Priority / Premium):
New PR = current + (offer / $50) × elasticity, capped at SP/ELV PR + 1pp for that range (or 20% fallback).
SP PR represents what SPs achieve at the same offer level — our natural ceiling if we became as aggressive.
New $/APC = per-slot net profit − offer. Click any Net $/APC cell to override the segment-average default with your actual data (national sales report).
Δ profit = (new APCs × new $/APC) − (current APCs × current $/APC).
SP/ELV: flat fee per APC (~$110). We don't bid — observational only.
Next refinement: bulk-load per-slot net profit & sale value from the national sales report.
