How Blow Score works
Blow Score measures how well a resort uses its snowmaking windows. When conditions are right for making snow, are they running their guns?
Prime — missing these is the worst
Good — solid windows, 70% weight
Marginal — barely worth it, 30% weight
Score = weighted hours confirmed / weighted hours available. Missing a prime hour carries a 1.5× penalty. 100 = perfect. 0 = wasted every opportunity.
