.calculate(score, distances, rounded = true) ⇒ Object

Calculate AGB score handicap as per David Lane’s original algorithm

Example:

>> distances = [
     {'range_in_meters' => 91.44, 'total_shots' => 72, 'target_diameter_cm' => 122, 'scoring_scheme' => 'IMPERIAL'},
     {'range_in_meters' => 73.152, 'total_shots' => 48, 'target_diameter_cm' => 122, 'scoring_scheme' => 'IMPERIAL'},
     {'range_in_meters' => 54.864, 'total_shots' => 24, 'target_diameter_cm' => 122, 'scoring_scheme' => 'IMPERIAL'}
   ]
>> score = 1105

>> result = AgbHandicap.calculate(score, distances)
