from 0.2 baseline, +0.0 at this ground

• 0.2 baseline — their last 10 games; only 0 this season, too few to blend
• −0.0 opponent leak — they concede 11.9/game vs a 12.8 league average
• +0.0 at this ground — averages 0.1 there against his own 0.3 in those same seasons — 114% of his own level (7 gm)
• vs them: averages 0.4 over 7 games — 171% of his own level in those seasons — 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.
