See net score page for more information about the allocation of handicap strokes.
In WHS for UK and Ireland a player competing from a set of tees with a different CR/par than other players receives more or fewer strokes for the round, depending on the difference between the CRs/pars. Therefore, for golfers competing in GB&I there is a separate calculator with the appropriate adjustment in the Playing Handicap calculation .
