market UCLA -2.5  ·  edge +2.6 (home)  ·  UCLA +6.1 vs CAL +3.5 + 2.7 HFA

The spread signal is SP+ only right now. Market is the consensus of 9 books. Positive edge = model likes California. Guide §2.

How the Yahn number is built — not a separate model
SP+ base+ EPA+ roster= rating
UCLA+5.4+0.7+6.1
CAL+3+0.5+3.5

SP+ is the backbone. EPA nudges toward raw efficiency (weight grows through the season — near zero this early). Roster = talent + returning production + transfer-portal net, fading to zero by week 5. Venue home edge: 2.7 (2.7 base + altitude / hostile bump; SP+ and SRS use a flat 2.5). Weights un-calibrated.

Only SP+ feeds this. Totals are noisier than spreads — the model's biggest UNDER edges cluster on blowouts and are mostly artifacts. Trust it most on games with a spread inside ~14. Guide §3.

Kalshi's market prices CAL to win 1% — about UCLA -31.4 vs the book's UCLA -2.5. 28.9-pt gap — the market rates UCLA higher than the book. Volume and open interest are total contracts on the game (each settles at $1), not a per-side split — they tell you how much to trust the price. Guide §9.

Weather

Forecast for the venue at kickoff time (nearest hour). Each row is a snapshot — expect it to firm up as the game nears; the timestamp is when that snapshot was taken.

Showing the 3 most recent of 10 readings.

Sustained wind ≥ 15 mph is the one weather factor that reliably moves a total (UNDER). Everything else is minor. Guide §4.

Injuries

No impact-player injuries listed. ESPN's CFB feed is thin — an empty report means "unknown," not "clean." Guide §4.

Picks

No pick logged. Most model disagreements never become picks — see guide §6 for the bar.
