• 0.2 baseline — 0.6 × season 0.2 (13 gm) + 0.4 × last 10 0.2
• −0.0 opponent leak — they concede 3.6/game vs a 3.9 league average
• at this ground: too thin to count (2 gm) — shown, adds nothing
• vs them: averages 0.0 over 2 games — evidence, never summed

Derived, not measured — plain arithmetic over his real games, shown in full. Adjustments can overlap (a game at this ground can also be a wet one); they add simply, and this note is the admission. Round 6: 1 — far outside his usual range; kept in the average, not smoothed away. Round 9: 1 — far outside his usual range; kept in the average, not smoothed away.
