Description
Sum each list and return newTotal - oldTotal as residual.
Weights, counts, and capacities determine an allocation only under a chosen normalization and rounding policy. A conserved total does not establish fairness or suitability.
Sum each list and return newTotal - oldTotal as residual.
When to use this tool
Use Milestone Weight Reassignment Residual when you need one explicit allocation or weight-change calculation.
How to use the tool and how it works
- Enter oldWeights, newWeights. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read oldTotal, newTotal, residual. Use the output convention below.
Require aligned nonnegative oldWeights and newWeights. Sum each list and return newTotal - oldTotal as residual.1

| Output field | Interpretation | Returned shape |
|---|---|---|
| oldTotal | Old Total | Required. Finite number. |
| newTotal | New Total | Required. Finite number. |
| residual | Signed residual using the convention in the calculation paragraph. | Required. Finite number. |

}Limitations and assumptions
- Weights need not sum to one; a zero residual does not prove that individual milestone allocations are unchanged or appropriate.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check totals, indivisibility, eligibility, and policy constraints across all recipients or criteria.
