Spreadsheet checks before running Damages Allocation in United States Federal

What the checker catches
Running a damages allocation spreadsheet in United States Federal (US-FED) matters can feel mechanical—until one hidden assumption breaks the math. The DocketMath damages-allocation checker helps prevent common spreadsheet failures before you finalize allocations for a claim set, settlement model, or damages report.
Below are the US-FED workflow failure modes the checker is designed to catch:
| Spreadsheet area | Typical error | Checker signal (what to fix) |
|---|---|---|
| Claim line items | Mixing claim types (or theories) without a consistent allocation key | Flags inconsistent “category” patterns across rows |
| Dates | Inconsistent date formats (e.g., MM/DD/YYYY vs YYYY-MM-DD) or missing required event dates | Highlights date parsing failures and missing required dates |
| Units | Summing quantities that aren’t comparable (e.g., per-unit vs lump-sum) | Detects mismatched unit labels or unusual numeric ranges |
| Rounding | Rounding during intermediate steps instead of at the end | Warns when rounding changes totals beyond a tolerance |
| Totals | Allocation totals don’t tie to overall damages inputs | Checks that row allocations reconcile to your target totals |
| Signs | Negative values for components expected to be non-negative | Identifies sign anomalies (e.g., unexpected negative damages components) |
| Assumptions | Allocation method selected but method parameters are blank | Flags “method selected but parameters missing” |
| Constraint logic | Constraints conflict (e.g., max cap < computed allocation, min floor > cap) | Surfaces constraint violations with specific deltas |
| Cross-sheet mismatch | Referencing the wrong sheet/tab range or using off-by-one row mappings | Flags orphan references and off-by-one reconciliation effects |
| Consistency across scenarios | Reusing old parameters across scenarios without updating scenario metadata | Identifies scenario metadata changes vs reused constants |
Pitfall: If your spreadsheet rounds each component (say, to 2 decimals) and then rounds totals again, reconciliation can drift by a meaningful dollar amount even when each row “looks right.” The checker catches reconciliation drift before you export.
Because federal damages models often include multiple components (e.g., base damages, enhancements, offsets, and other model-dependent components), the checker prioritizes reconciliation and internal consistency—not just whether the sheet “calculates.”
When to run it
To get the most value from the DocketMath damages-allocation checker for US-FED usage, run it at these stages:
Before you lock inputs
- After you import or paste claim data
- Before you apply formulas for allocations
Goal: catch date parsing issues, missing fields, and category inconsistencies early.
After the first full calculation pass
- Once all formulas populate
Goal: confirm allocations reconcile to target totals and that constraints behave as expected.
After you change any model driver
- Allocation method
- Caps/floors
- Tolerances
- Scenario parameters
Goal: ensure changes didn’t silently break reconciliation or shift unit assumptions.
Before exporting to a stakeholder format
- CSV, PDF-ready tables, or a settlement summary sheet
Goal: prevent the common “working sheet vs export mismatch” problem—where the export uses a different range, mapping, or rounding behavior than the working model.
A practical workflow that usually works well:
- ✅ Populate inputs (claims, categories, dates, quantities)
- ✅ Run the checker (data quality pass)
- ✅ Apply allocation formulas
- ✅ Run the checker again (reconciliation + constraints pass)
- ✅ Export only after the checker reports no critical errors
If you run multiple scenarios (e.g., alternative allocation methods or different claim groupings), treat each scenario as its own run. That makes it easier to spot where scenario parameters were unintentionally reused.
Try the checker
You can run the damages allocation checker directly here: /tools/damages-allocation.
If you want to connect this step to a broader spreadsheet hygiene process, consider starting with /tools/spreadsheet-checker first, then proceed to damages allocation. This two-step approach is helpful when spreadsheets have been edited across versions or by multiple contributors.
What to expect:
- You provide the spreadsheet data (or paste structured inputs).
- DocketMath applies US-FED jurisdiction-aware rules to check allocation consistency.
- The tool returns:
- A pass/fail summary
- A list of specific issues (often pointing to the relevant row/field)
- Suggested next actions such as verifying date format, confirming reconciliation, or checking constraints
What to prepare before you run
Checking these items beforehand increases the quality of results:
How outputs change when you fix issues
The checker isn’t only a validator—it helps prevent incorrect allocation math from reaching your outputs:
- If date parsing fails, event timing logic can shift allocation windows across claims.
- If units don’t match, per-unit allocations can inflate or deflate distributions.
- If rounding is applied early, reconciliation can drift even when individual lines appear reasonable.
- If row totals don’t tie to target totals, exports and stakeholder summaries may show inconsistent figures.
Warning (non-legal): Don’t assume “it calculated” means “it allocated correctly.” A spreadsheet can compute successfully while violating reconciliation constraints—especially if formulas reference the wrong range, mapping, or rounding approach.
