Preserve facts, units, model choices, warnings, and source basis with the chart.
Compare baseline, range, anthropometric, and advanced research behavior when appropriate.
Use exports as professional work materials that still require expert interpretation.
Expert witnesses need tools that preserve inputs, test assumptions, visualize alternatives, and make the basis of a calculation easier to audit. DUI Professional can organize alcohol dose, timing, specimen information, model parameters, warnings, and report annotations. The opinion remains the expert's responsibility.
Transparency Is the Core Feature
Expert witnesses do not need software that pretends to be the expert. They need tools that preserve inputs, test assumptions, visualize alternatives, and make the basis of a calculation easier to audit.
DUI Professional can organize alcohol dose, timing, specimen information, model parameters, warnings, and report annotations. The opinion remains the expert's responsibility.
What an Expert Can Audit
An expert using DUI Professional may review drink dose and standard-drink equivalents, first-drink and last-drink timing, per-drink distribution, absorption assumptions, food status, distribution assumptions, elimination assumptions, keypoint selection, measured-test timing, specimen type, unit conversions, warnings, limitations, and source basis.
When one of those inputs is uncertain, the report should make that uncertainty visible. A report that documents uncertainty is usually more useful than one that hides uncertainty behind a smooth curve.
Model Comparison and Alternative Assumptions
Different models answer different questions. Standard Widmark, ASB-oriented range modeling, Watson Total Body Water, delayed absorption scenarios, and advanced research models should not be treated as interchangeable.
Model comparison can show whether a result is sensitive to distribution, elimination, absorption, or body-water assumptions. It does not mean every model is appropriate for every case.
Reports for Expert Review
Exports should be treated as professional work materials. They may help prepare testimony, consultation, or demonstratives, but they do not create expert opinions by themselves.
The report should preserve the chart, model names, units, parameters, user overrides, warnings, assumptions, citations, and input audit. That is the material a qualified reviewer needs before deciding what, if any, opinion is supported.
Demonstrative Use
A chart can help explain timing and assumptions, but admissibility and courtroom use depend on the jurisdiction, case facts, disclosure, witness foundation, and court rulings. DUI Professional should support that foundation by making the calculation easier to inspect, not by overstating the result.
Frequently Asked Questions
Does DUI Professional create expert opinions?
No. It organizes scenario inputs and assumptions. Opinions remain the responsibility of qualified experts.
Why compare models?
Model comparison can show whether an output is sensitive to distribution, elimination, absorption, or body-water assumptions.
Can an expert use the report appendix?
Yes. The appendix can help audit inputs, parameters, warnings, assumptions, and sources before any opinion is formed.
