How Ringer calculates it

Σ(radial distance from confirmed target)measured explicit green targets

Evidence rules

IncludedOnly current, confirmed shots assigned to this category with usable start and finish evidence.

ExcludedDrafts, voided or superseded revisions, non-strokes, unusable locations, and attempts missing a measurement required by this formula.

DenominatorThe number of eligible attempts after the stated exclusions—not every hole or every round by default.

Missing dataIf no eligible denominator remains, Ringer returns unavailable and displays “—”, never 0% or NaN.

Classification

Derived only when the golfer explicitly confirmed a green target and both target and finish coordinates are usable. The target may differ from the pin; inferred or unknown intent is excluded.
