you make some extremely valid points. You should have a right to see the sourcecode as there is no harm in doing so.

I work for a pharmaceutical company, and someone at work just informed me of something funny when it comes to reading your blood alcohol level. Heres a some quotes from a site that explains it best.
Body Temperature: The widely used blood-to-air partition ratio of 2100 is based on a normal body temperature of 98.6°F. A higher body temperature of the individual will overestimate the actual BAC because of the higher volatility (or vapor pressure) of liquids like alcohol at a higher temperature. An elevation in body temperature of 1°C (1.8°F) results in a 7% higher value in the result since the air in the lungs will contain an artificially higher amount of evaporated alcohol. Therefore, a person with a body temperature of 100.4°F, and with an actual blood alcohol of 0.0935%, will register a value of 0.10% by the breath test. Be careful if you have a cold or the flu.
Cellular Composition Of Blood: Blood contains suspended cells (e.g. red and white cells) and proteins, and is therefore only a partial liquid. The partition ratio of 2100 is based on an average cell volume 47%. Some of this cell volume is tissue, and at 47% cell volume, 81.5% of the blood volume is liquid in which the alcohol is actually dissolved. A person with a lower cell volume will have a falsely elevated blood alcohol level based on a breath test since the amount of alcohol in 2100ml of lung breath will be dissolved in a slightly higher amount of liquid, and hence have a lower concentration. Cell volume values range from 42% to 52% in males, and 37% to 47% in females. This variability will only have a small impact on BAC (ranging from -2% to +5%) so don't rely on it in court.
The ratio of breath alcohol to blood alcohol is 2100 to 1 (and called the partition ratio), so the alcohol content of 2100 milliliters of exhaled air will be the same as for 1 milliliter of blood. The maths are simple from there and leads to blood alcohol readings expressed as a percentage of alcohol in the blood.The partition ratio can vary between 1700 and 2400 depending upon the individual and local environmental conditions, leading to a breath analysis reporting either a higher or lower calculated blood alchol reading.

with all those variables i would demand the source code too, weird how a few minutes can change your opinion =X

once again though, if his BAC was way over the limit, what are the chances even with these variables that it is wrong.

Should have fined him for stupidity and obstruction.
