The books’ cut: 5.3%, the margin built into the odds

Home field

South Dakota is worth +4.9 points (±9.4) more at home than on the road since 2018 — middle of FBS, 64th percentile.

57% at home, 14% on the road against FBS opponents (4-3 home, 2-12 away).

Our model gives every stadium the same flat 2.3-point home edge (why); the books use about 3. Against the closing line this stadium reads +6.0 at home vs. away over 57 games — inside the ±7.0 noise, so the flat number is the honest one here.

Indoors — dome hosts have beaten the number by about a point and a half more than outdoor ones, on a small sample. The visitors travel about 1,054 miles to get here.
