What this is
Fiscal-year windows differ: SM 18 Nov–31 Mar (4.4 months), Z-A 16 Oct–31 Mar (5.5 months), Arceus 28 Jan–31 Mar (2 months), so Arceus is not comparable to Z-A on FY units; use the first-week row for Legends vs Legends.
The values
- Z-A all against Sun/Moon: 0.828
- Z-A against Arceus first week: 0.892
Some detail is too fine to show here; it is kept in the trainer’s notes.
