Use public profiles, custom drinks, ABV, volume, and per-drink timing for dose documentation.
Compare baseline, range, body-water, and expert-review research scenarios without hiding assumptions.
Carry model names, units, warnings, and citations into professional reports.
DUI Professional is a BAC simulation workspace built around the facts professionals actually review: drinks, ABV, volume, drinking times, body inputs, food and absorption assumptions, selected model, keypoint time, measured result, warnings, and report output.
Build the Dose From Real Drink Data
A BAC simulation starts with the drinking history, not just a total number of drinks. DUI Professional lets users select public drink profiles, create private custom drinks, adjust partial servings, and document ABV, volume, and timing.
That matters because real beverages do not always match shorthand descriptions. A 12-ounce beer, high-ABV craft beer, wine pour, mixed drink, liqueur, or partial serving can represent different ethanol doses. DUI Professional keeps those details connected to the chart and report so the modeled result can be reviewed later.
Model Timing, Not Just Totals
Simple BAC tools often spread alcohol evenly across a drinking window. Real drinking patterns can be front-loaded, back-loaded, clustered, interrupted, or overlapping. DUI Professional lets users place individual drinks on the timeline and set individual consumption lengths.
Per-drink timing can affect absorption, peak timing, and the modeled value at a key event. The feature does not turn an assumption into a measured fact. It makes the assumption visible.
Compare Models Without Hiding Assumptions
DUI Professional preserves the familiar Widmark workflow while allowing optional model comparison. Depending on the available facts and the user's professional purpose, the simulator can compare standard Widmark output with ASB-oriented range modeling, Watson total body water, delayed absorption scenarios, and advanced research models for expert review.
The point is not to market exact BAC. The point is to show how the result changes when assumptions change.
Charts and Reports
The chart is the working surface for peak BAC, range lines, selected model overlays, keypoint values, consumption timing, and model differences. The report should carry the same context: drink inputs, subject variables, model names, units, warnings, assumptions, and citations.
For professional use, the audit trail matters as much as the chart. A report is stronger when a reviewer can see what facts were entered, what assumptions were selected, and what limitations were preserved.
Who Uses This Workflow
DUI attorneys may focus on driving-time keypoints and rising-BAC questions. Prosecutors may use the workflow for screening, witness preparation, and training. Toxicologists and expert witnesses may use it for assumption review and model comparison. Aviation, workplace, law enforcement, and alcohol-education users may use it for training and timeline education.
Different users may ask different questions, but they need the same discipline: clear inputs, visible assumptions, and careful reporting.
A Professional Workflow
A typical review starts by naming the scenario, entering subject variables, and selecting the relevant keypoint. The user then adds drinks from the database or a private profile, adjusts serving amounts, and places each drink on the timeline. If the drinking history is uncertain, the user can build more than one scenario.
After the drinking pattern is entered, the user selects the calculation model. For an education scenario, the standard Widmark workflow may be enough. For forensic review, the user may compare range or body-water assumptions. Advanced research models should remain clearly identified as expert-review tools.
What Makes the Software Credible
DUI Professional should not promise that a chart proves impairment, innocence, admissibility, compliance, or causation. Its value is that it keeps units visible, preserves user inputs, separates measured facts from assumptions, and documents warnings when required information is missing.
Credible BAC modeling does not hide uncertainty. It shows it.
Frequently Asked Questions
Is DUI Professional a BAC calculator?
It includes BAC calculation logic, but it is better described as simulation software because it models alcohol concentration over time and preserves assumptions.
Why does per-drink timing matter?
Because real drinking is often not evenly distributed. Per-drink timing can affect absorption, peak timing, and the modeled BAC at a key event.
Are reports court-approved?
No. Reports are professional work materials. Legal use depends on case facts, witness foundation, jurisdiction, disclosure, and court rulings.
