Handicap Index Safeguards
What is my Low Handicap Index™ and why is it displayed in my scoring record?
A Low Handicap Index is the lowest Handicap Index® achieved over the 365-day period preceding the most recent score in your scoring record. The Low Handicap Index serves as a reference point against which your current Handicap Index can be compared.
A Low Handicap Index is established once you have 20 scores in your scoring record. (Rule 5.7, Rules of Handicapping)
