from 28.2 baseline, −1.0 opponent leak

• 28.2 baseline — their last 10 games; only 0 this season, too few to blend
• −1.0 opponent leak — they concede 355.7/game vs a 368.4 league average
• +0.9 at this ground — averages 28.6 there against his own 27.6 in those same seasons — 103% of his own level (7 gm)
• vs them: averages 31.4 over 5 games — 115% 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.
