Model Library
Expert Analytics is a public manual section for assumption-dependent BAC modeling.
These pages are written for attorneys, toxicologists, expert witnesses, trainers, and advanced users who need more than a one-line feature description. The manuals describe what each model does, which inputs matter, where the model appears in the simulator, how the chart should be read, and how the report annotations preserve assumptions for review.
Legacy default
Standard Widmark
The preserved DUI Professional default model for dose, distribution, absorption timing, elimination, keypoint review, and backward-compatible report output.
Open manual
Forensic range
OSAC Forensic Range
A forensic range model that emphasizes Vd and elimination ranges, post-absorptive assumptions, uncertainty, and clear reporting rather than a single retrograde value.
Open manual
Body water
Watson Total Body Water
An anthropometric total-body-water model using age, height, weight, and sex/body-water basis, with sanity checks, optional composition review, and explicit reporting.
Open manual
Research model
Michaelis-Menten Low-BAC
An advanced nonlinear terminal-elimination scenario for expert review, used to explore low-BAC sensitivity and explain why linear extrapolation has limits.
Open manual
Research PK
Norberg Two-Compartment
An advanced pharmacokinetic comparison model for absorption, distribution, and elimination variability, exposed for expert review and education rather than default reporting.
Open manualProfessional framing
Modeled BAC values are estimates based on stated assumptions and inputs. They are not measurements, medical advice, legal opinions, or a promise that a calculation will be accepted in any proceeding. The manuals are intended to make DUI Professional model use more transparent and reviewable.
