Two plans for the investor: Plan A ~180M, Plan B ~225M THB; Pheenix at OMS +20 %

User (October 2026): price the Pheenix galvanics line at OMS's reference
plus 20 %, and work on a new business plan in two versions, one at
roughly 180M THB and one at +25 %; the plans do not include contingency;
Plan A keeps every machine and uses cost levers only.

- total-investment.md: Pheenix block 324k to 445k USD (OMS 4-cell wet
  room with know-how transfer, EUR 234k to 321k, plus 20 %; was 320k to
  650k estimate); launch plant now ~161M to 285M THB with contingency,
  midpoint ~223M. New section "Two plans": Plan A = launch plant with
  solar PPA, metrology launch tier, corridor later, cassette and CD-R
  later, rented crane, Chinese boilers and compressor: subtotal ~161.7M
  + ramp-up reserve 10 to 20M = ~177M THB (127M to 226M). Plan B = second
  Duplex at launch (five presses), everything in: subtotal ~209.2M +
  reserve = ~224M THB (162M to 286M). Contingency listed as not in
  either price (~24M / ~31M at 15 %). The 180M / 216M answer marked
  superseded.
- revenue-model.md: operating pictures of both plans at 60 % specials.
  Plan A central EBITDA 1.73M USD, operating profit 1.34M, payback ~3.1
  yr on the plan price; adverse loses money. Plan B (1.0 / 1.25 / 1.5M
  records) central EBITDA 3.14M, operating profit 2.63M, payback ~2.2 yr;
  adverse just covers depreciation; needs ~1.25M records sold.

+## Operating pictures of Plan A and Plan B (October 2026)
+
+The business plan comes in two versions
+([total investment](total-investment.md#two-plans-a-at-180m-thb-and-b-at-225m-thb-october-2026)):
+**Plan A** (~177M THB, the launch plant with six cost levers, three
+presses) and **Plan B** (~224M THB, the second Duplex at launch, five
+presses), both priced without contingency and with the ramp-up reserve.
+Same method and cases as above, at the planned 60 % specials (estimates):
+
+- **Plan A** runs the launch plant, so volume, price, direct cost, title
+  services and overheads are those of the table above; only the
+  depreciation follows its lower capital: the high end of Plan A's blocks
+  (6.25M USD) over 10 years, the midpoint (4.90M USD) over 12.5, the low
+  end (3.56M USD) over 15. The solar PPA adds its power price to the
+  energy line (~0.03M USD a year in the calculator), not shown here.
+- **Plan B**'s five presses are not Duplex-limited at 60 % specials: the
+  four semi-automatic presses (240 to 320 records an hour) carry the
+  specials and the Classic the rest, so volume is the five-press band,
+  **1.0 / 1.25 / 1.5M** records. Direct cost per record is the five-press
+  table's 2.58 / 1.94 / 1.30 USD (the same payroll over more records);
+  title services 300 / 375 / 400 titles at 580 / 1,155 / 1,730 USD and 60
+  / 65 / 70 % contribution (the five-press table's 0.10 / 0.28 / 0.48M);
+  depreciation on Plan B's blocks: 8.07M USD over 10 years, 6.34M over
+  12.5, 4.61M over 15.
+- **Payback** is counted on the whole plan price including the ramp-up
+  reserve (Plan A 3.86M / 5.35M / 6.85M USD, Plan B 4.92M / 6.79M /
+  8.67M USD from the low to the high end).
+
+| USD/yr | A adverse | A central | A favourable | B adverse | B central | B favourable |
+|---|---|---|---|---|---|---|
+| Records | 0.58M | 0.74M | 0.90M | 1.0M | 1.25M | 1.5M |
+| Blended price (60 % specials) | 3.76 | 4.49 | 5.27 | 3.76 | 4.49 | 5.27 |
+| Direct cost | 2.70 | 2.00 | 1.35 | 2.58 | 1.94 | 1.30 |
+| Pressing contribution | 0.61M | 1.83M | 3.51M | 1.18M | 3.19M | 5.96M |
+| Title-services contribution | 0.07M | 0.23M | 0.48M | 0.10M | 0.28M | 0.48M |
+| Cash overheads | 0.45M | 0.33M | 0.20M | 0.45M | 0.33M | 0.20M |
+| **EBITDA** | **0.23M** | **1.73M** | **3.79M** | **0.83M** | **3.14M** | **6.24M** |
+| Depreciation | 0.62M | 0.39M | 0.24M | 0.81M | 0.51M | 0.31M |
+| **Operating profit** | **-0.39M** | **1.34M** | **3.55M** | **0.02M** | **2.63M** | **5.93M** |
+| Revenue | 2.28M (~75M THB) | 3.65M (~120M THB) | 5.41M (~179M THB) | 3.93M (~130M THB) | 6.05M (~200M THB) | 8.60M (~284M THB) |
+| Payback on the plan price (EBITDA, mature year) | ~30 yr | ~3.1 yr (2.2 to 4.0) | ~1.0 yr | ~10.5 yr | ~2.2 yr (1.6 to 2.8) | ~0.8 yr |
+
+What it says:
+
+- **Plan A** breaks even on operating profit at **~0.2 million records a
+  year**; its adverse corner still loses money, because it would need
+  ~0.9 million records to cover depreciation and the three presses make
+  0.58 million at that rate.
+- **Plan B** breaks even at ~0.22 million records and its adverse corner
+  just covers depreciation (~1.0 million records needed, 1.0 million
+  made): more presses spread the same crews, overheads and title services
+  over more records. Its central EBITDA is ~1.8 times Plan A's for ~27 %
+  more money.
+- **But Plan B only earns this if the records sell.** Its central case
+  needs ~1.25 million records a year, ~0.75 million of them special
+  editions, against 0.74 million for Plan A; nothing in the market data
+  so far shows that demand (roadmap item 1). The ramp to that volume is
+  longer, and the ramp-up reserve (10M to 20M THB) is the same estimate
+  as for Plan A.
+- **The caveats above hold for both:** central EBITDA margins of ~47 %
+  (A) and ~52 % (B) are far above the 15 to 25 % pressing plants earn,
+  the cost of specials is not in the direct cost yet, and neither plan
+  carries a contingency. Treat the adverse columns as the honest ones.
+
+The [calculator](../fleet-calculator.html) presets, at the team's
+planning rates (3 records a minute per Duplex system) and its own cost
+build-up, give: **Plan A** at 850k records EBITDA 2.04M USD, payback 2.4
+years on the investment, cash payback in year ~3.9 and ~25 % IRR over ten
+years with the reserve in year 0; **Plan B** at 1.25M records EBITDA
+3.25M USD, payback 2.0 years, cash payback in year ~3.3 and ~32 % IRR
+(pre-tax, pre-financing, estimates).
