from 14.2 baseline, +0.7 at this ground

• 14.2 baseline — their last 10 games; only 0 this season, too few to blend
• −0.5 opponent leak — they concede 355.7/game vs a 368.4 league average
• +0.7 at this ground — averages 20.8 there against his own 19.7 in those same seasons — 105% of his own level (8 gm)
• vs them: averages 21.0 over 6 games — 108% 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.
