Calculation and observed tool result
Before
10 m² × 25 g/m² = 250 g/application; floor(2,000 ÷ 250) = 8 applications. Follow the product rate.Recorded quantity: 2,000 g.
After
10 m² × 25 g/m² = 250 g/application; floor(1,750 ÷ 250) = 7 applications. Follow the product rate.Recorded quantity: 1,750 g.
What the result means
The new snapshot represents seven applications instead of eight.
Limits of this example
The actual application rate remains the user’s responsibility.
