Dosing Accuracy with delivered dose mass of 63 g: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop delivered dose mass to 63 g, then walk the calculation through step by step. Dosing Accuracy quantifies how far a delivered dose deviates from its target mass, expressed as a percentage of a reference recipe amount.

The inputs for this scenario

  • Delivered dose mass: 63 g (the input this scenario stresses; the baseline uses 125)
  • Target dose mass: 100 g (held at the documented default)
  • Nominal recipe dose: 100 g (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Dosing Accuracy margin = available value - required value.
  • Margin works out to -37 % at these inputs, and this is the headline figure for the scenario.
  • Absolute margin works out to -37 value at these inputs.
  • Available amount works out to 63 value at these inputs.
  • Required amount works out to 100 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where delivered dose mass sits at 125 g and the headline result is 25 %, this scenario comes in 248% below the baseline at -37 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to delivered dose mass, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. A positive margin only tells you the direction and size of the average deviation, not its repeatability; a doser that alternates over and under can average near zero yet still fail.
