Yield = dose x ratio.

For example, if your dose is 20g and your ratio is 2.5, your yield should be 50g.

You should use your scales under your cup and stop the shot when it reaches the target yield.

The important thing to keep constant is the ratio. So, if you need to lower the dose to 18g, for example, because you can’t fit 20g in your basket, your yield should be 18×2.5=45g.
