Thanks to cobaltm for his guidance for this formula.
The formula for the handicaps is based on 60 being the entry to Tour Legend tier, that is the scratch score. Any calculated par average above or below that will be plus or minus. The minus one (below) is because nobody ever gets an exact average (I am reliably informed). Any number above or below decimal .5 should be rounded up or down to a whole number. Eg; 66.333 = 66
Example 1
Scratch = 60
Players average over 5 matches = 67 - minus1= 66
Handicap -6
Example 2
Scratch = 60
Players average over 5 matches = 59 -1 =58
Handicap +2
The handicaps are calculated from the last five18 hole, stroke play club tournaments, (excluding par 5 holes and par 3 holes t/ments).
