Greensomes handicaps are
calculated by multiplying the lower handicap by 0.6 and the higher
handicap by 0.4,
before adding the two results and then rounding to the nearest whole
number.
Alternatively, you may use the table below.
Look up one handicap in
the top or bottom row of this table and the other handicap in the left or right hand
column.
The Greensomes handicap can be found where the two lines intersect. (e.g. handicaps of 10 and 20 give a Greensomes handicap of 14.)
