What this is
This is a CORRECTION, not a conflict between sources: the CY-weighting proxy is superseded by the window rates.
The values
- Rows using 149.57: 96
- Rows using 150: 29
- Rows using 140 155 band: 13
Some detail is too fine to show here; it is kept in the trainer’s notes.
Where it comes from
Our calculation from other figures in the trainer’s notes:
- EstimateJpy per usd fiscal period average from calendar years, year to March 2018-year to March 2026; year to February 2021-year to February 2026; 2020-2025
- FiledFx rate register TPC fy2 ($/¥, EUR/¥: year average and year-end), TPC year to February 2017–year to February 2026 (Mar–Feb; FY-end = last business day of February)
- FiledFx rate register nintendo fy3 ($/¥, EUR/¥: stated year average and stated year-end), Nintendo year to March 2016–year to March 2026 (Apr–Mar) + year to March 2027 assumption
Show the working
- built FY3/N = 0.75×CY(N−1) + 0.25×CY(N), TPC FY2/N = 10/12×CY(N−1) + 2/12×CY(N), and set FY3/26 = FY2/26 = CY2025 = 149.5686
- Against the register : FY3/26 149.57 vs 150.72 → −0.76%
- FY2/26 149.57 vs 149.9
