Is there such a thing as a “minus handicap”, sorry I don’t know the correct term.
If you don't have a positive number handicap, you're called a "scratch golfer".
I don't believe I've ever heard of a "minus handicap".
Professional golfers and good amateurs are expected to be at par or below.
Technically a minus handicap is for players like Biden who are terrible where strokes are basically taken away from their score.
For example, let’s say I have a -18 handicap on a par 72 course I would logically expect to shoot a 90 actual score or a 72 after the -18 handicap is applied.
A positive or plus handicap works just the opposite, strokes are added to your scores, as you can imagine the only players with a positive or plus handicap low amateur or near professional golfers.
Remember the purpose of the handicap is to allow people with a wide range of golf skills to play against each in as fair of a way as possible.
It’s a plus handicap actually. I have a mini-tour player friend w/ a usga index 0f +5. He’s shot some 60’s, 61’s, but doesn’t actively enter scores. He thinks Peak Tiger would have been close to +10.
That means if you play him w/ a 10 handicap, you’re now getting 15 shots instead of 10.
