The lower your initial handicap is, the less the points count. If you are below 4.0 (or thereabouts), you can only lower your handicap in official tournaments.

If you want to raise your handicap, you can only raise it 0.1 each round no matter how many (or few!) points you collect. Additionally, you can only raise your hcp if you pre-announce it or if it is a tournament.
