Calculation and observed tool result
Before
Stock = 0 × 1500 + 300 = 300 g; floor(300 ÷ 250) = 1 refillsRecorded quantity: 300 g.
After
Stock = 2 × 1500 + 300 = 3,300 g; floor(3,300 ÷ 250) = 13 refillsRecorded quantity: 3,300 g.
What the result means
The delivery adds 3,000 g without altering the 300 g open remainder.
Limits of this example
