All GP scores are based upon Stableford. There is no need to to finish a hole. You just record NR for any hole started but not finished and NS for any hole not started.
On your England Golf record a NR on a hole will be shown as a net double bogey in black with an asterisk next to it.
Whether or not your handicap stays still, goes up or down depends on how many scores you have on your record and if you have 20 it depends on the score that one knocks off your record.
