What adjustment is made to the mix line when cutting ice in half for a light ice drink?

When preparing a light ice drink, the mix line is adjusted to account for the reduced volume of ice. By cutting the ice in half, the space that would normally be occupied by the ice is now available for the beverage mix. This means that to maintain the appropriate beverage concentration and volume, the mix line must be increased to fill the cup appropriately.

Increasing the mix line compensates for the smaller amount of ice, ensuring that the drink still has the right balance and intensity of flavor. This adjustment helps to ensure that the final beverage still offers the intended taste experience, despite the significant reduction in ice.
