Charlton Athletic vs Norwich City

The model rates this medium confidence. Charlton's last five home fixtures produced corner totals of 10, 12, 17, 11, and 9, giving a home match average of 11.8, which sits comfortably above the Championship baseline of 10.2. Norwich's away games tell a quieter story: their last five yielded totals of 5, 8, 11, 8, and 11, averaging 8.6 per match. The model's predicted total of 9.82 lands fractionally below the league baseline, but the two team profiles are pulling in opposite directions, and how that resolves at The Valley is genuinely open.

Charlton's 17-corner home outlier in the last five is real variance, and it skews their short-window average upward in a way the model has to account for. That caps confidence. Norwich's away range stretches from 5 to 11 across the same window, and neither profile is stable enough to anchor a high-confidence read. The medium rating is a direct output of that instability.

Calibration matters here. Medium confidence sits below the high confidence tier, not adjacent to it, and sizing positions as though the distinction doesn't matter is where edge gets eroded across a long run of picks. The signal exists; so does the structural uncertainty the model's rating captures.
