Topic Brief: Sales Forecasting and Break Even

Provenance (checked 2026-09-28): research/veridian/WBS12-verified-facts.md read in full and grepped for every sales-forecast/break-even/contribution/margin-of-safety hit (spec 2.3.2.1–2.3.2.3); content/veridian/ technique-hub/wbs12/codex-deep-dive-sales-forecasting-and-break-even.md read in full — that document's own freshly re-extracted primary-source work (five series opened directly from the local archive with pdftotext -layout and checked bullet-by-bullet) is cited here by series and question, not re-derived; signal-frequency-and-boundaries.md read in full to confirm this brief doesn't restate its section-level (2.3.2-wide, both sub-topics combined) frequency table; content/veridian/curriculum/wbs12/sales-forecasting- and-break-even.ts read in full (its mechanism, worked chains and level-exemplars are cross-referenced, not reproduced); content/veridian/question-bank/wbs12.ts grepped for this topic's terms — zero hits, nothing to duplicate. No new primary-source extraction was done for this pass — every claim below traces to one of the two research documents named above, cited inline by series and question. Denominator used throughout: 18 series (the facts bank's own 16, June 2019–October 2024, plus January and June 2025 per the CODEX deep-dive's own provenance note) — the same denominator the sibling SIGNAL documents in this folder use.

#WBS12 SIGNAL — Topic Master Brief: Sales Forecasting and Break-Even

Spec 2.3.2, items 1–3. This is a frequency-and-pattern summary, not a re-teach — mechanism, worked numbers and full trap detail live in sales-forecasting-and-break-even.ts (curriculum) and codex-deep-dive- sales-forecasting-and-break-even.md (technique-hub). What this adds: which real series have actually tested this specific topic, at what tariff, in what recurring shape — pulled into one place rather than spread across two long documents.

#1. Every real series confirmed testing this topic

Seen in 10 of 18 series checked. Eight carry a real question with a stated tariff; two more name the topic in a real extract or examiner-report comment without a tariff-anchored sub-question documented in the material reviewed — kept as a separate, thinner tier rather than merged into one inflated count.

(Citations: all ten per the CODEX deep-dive's exam-angle synthesis table, itself built from the facts bank plus five series opened directly from the primary local archive for this specific topic — see that document's own provenance note for exact file paths.)

Two thinner hits, topic named but no tariff documented in the material reviewed: October 2019 (Q2c, examiner report: "candidates confused market research for sales forecasting") and October 2021 (Symington's, sales forecasts read against a change in the national unemployment rate). These are the two series folded into the 10-of-18 total above, alongside the eight tariff-anchored hits.

A genuine null result, stated rather than papered over: June 2025 was checked directly and contains no dedicated sales-forecasting-or-break-even question that series [CODEX deep-dive].

A cruder, separate signal: a term-frequency sweep of all 16 archived 2019–2024 mark schemes and examiner reports (question papers excluded) finds "break-even" in 14 of 16 and "sales forecast" in 9 of 16 [CODEX deep-dive] — but this counts any mention, including the paper's generic "QS5: Calculate cost, revenue, profit and break-even" tag shared with unrelated questions, so it is a floor on exposure to the term, not a count of dedicated questions on this topic. The 10-of-18 figure above, built from named questions and businesses, is the more precise number.

#2. The mark-tariff pattern

Across the eight tariff-anchored hits: one Define (2), two Explain (4, one each direction), one unlabelled Calculate, two Analyse (6), two Discuss (8, one shared with an adjacent 2.3.5.1 angle), and one Evaluate (20). That is a real anchor at every tariff on the paper except the 10-mark Assess — no real Assess-level question built specifically around sales forecasting or break-even was found in any of the 18 series checked [CODEX deep-dive]; the existing lesson's own Assess exemplar is VERIDIAN-original for exactly this reason, not a reproduction of a real question.

Section placement leans toward Q1: of the eight tariff-anchored series, four place their question in Section A (Jan 2021, Jan 2023, Oct 2023, Jan 2025), three in Section B (Oct 2020, Oct 2022, Jun 2023), and one as the Section C 20-mark essay (Jun 2021). Too small a sample to call a rule, but the lean toward Q1 is real and worth knowing rather than assuming an even spread.

#3. Recurring context/angle

The clearest repeated pattern is a directional-reasoning rule, confirmed independently in both directions two years apart. January 2021's Greggs question credits "the break-even point may decrease" from a falling variable cost; January 2023's question credits the mirror case, "it was necessary to say it would increase." Same knowledge-mark rule, opposite real cost movements — evidence the paper tests following the mechanism from a stated change, not a memorised "costs up, break-even up" association [CODEX deep-dive, citing MS Jan 2021 and the verified-facts file's Jan 2023 entry].

The confirmed error pattern sits on the mechanical link between extract and answer, not the concept itself. January 2021's report penalised candidates who copied the extract's raw variable-cost figures without recalculating contribution — the derived figure was required, not the given one. October 2022's report confirms a distinct reading trap: some candidates calculated variable cost per unit when the question asked for the total [CODEX deep-dive, citing ER Jan 2021 and the verified-facts file's Oct 2022 entry].

One real anchor tests the model's own stated assumption directly: June 2023's Wilson question pairs a break-even limitations Analyse (6) with a Discuss (8) on a Thai Baht appreciation — a real exporter for whom the spec's own "constant selling price and variable cost" assumption (2.3.2.3f) is genuinely fragile. One real anchor pairs break-even with a strategic choice rather than a cost shock happening to the business: June 2021's 20-mark question weighs advertising against raising price as two opposite-direction ways to change the same margin-of-safety gap. One real anchor tests aggregation itself: October 2023's Arditi Tours question shows a whole-day margin of safety of 8 concealing two individual departures running below break-even — an average-vs-disaggregated trap with no other confirmed precedent in the 18 series checked.

#4. If this topic appears — what to expect

Most likely shape, based on what has actually happened in 10 of 18 series: a short Define, Explain or Calculate question in Section A, built from a single cost/price change or a straightforward break-even or margin-of-safety figure — and if it's an Explain question, expect the knowledge mark to require a stated direction (increase or decrease), not just an assertion that break-even "would be affected." A 6-mark Analyse or 8-mark Discuss is next most likely, confirmed three times across two series (Jun 2023, Oct 2023), each built around a genuine twist on the basic mechanism — an assumption the model relies on breaking down (exchange rate), or a whole-period average concealing a below-break-even component — rather than a bare recalculation. A 20-mark Evaluate has one real precedent (Jun 2021), framed as a choice between two named strategies for closing the same margin-of-safety gap. No real 10-mark Assess precedent exists in the 18 series checked — if this topic appears at that tariff, it would be a first, not a repeat. Whatever the shape, the confirmed traps sit on the mechanical step between extract and answer — recalculating rather than copying, total rather than per-unit, disaggregated rather than averaged — more consistently than on the underlying concept.
