Upswing is a positive stretch where results are running well and the overall trend is better than usual.

What does it look like in practice?

In poker, an upswing can mean a strong run in all-ins, runouts, and pots won. In betting, it can mean a streak of winning bets where the balance grows faster than normal. The term does not mean the player has suddenly become unbeatable. It simply describes a period where results are moving upward. In simple terms, an upswing is a good run that may come from both strong decisions and short-term luck.
