A pint of vodka contains 8.5 standard drinks (US). Consumed over an 8-hour period. Since alcohol (EtOH) is metabolized at a steady albeit individual rate beginning with first drink. That benefits your cause.
It sounds like you may be confusing EtOH metabolism with EtG metabolism. They follow two different models. EtG is created as EtOH is metabolized. It's a by-product, a direct metabolite that is then eliminated via a process known as enzyme kinetics. Not the same process as EtOH.
The problem is we don't know how much EtG is produced by any given individual. That is highly variable between individuals but also varies by time and condition within the same individual. After drinking the exact same amount of alcohol it is quite possible to be EtG clear at 48 hours on one occasion and test positive at 60 hours on another.
Any attempt to time alcohol consumption in relation to EtG synthesis let alone elimination is very risky. You seem to be counting on the fact that the test is unreliable. And it certainly is. EtG is used only in the non-regulated drug testing
field. There are no uniform standards that apply to this test. That is a decision left to the testing agency and the laboratory. The result is that not only is the test unreliable but is often carelessly performed. Most labs now offer the test without confirmation
and that adds an additional 15% margin of error. So the unreliable and unpredictable nature of the test is just as likely to accrue to you detriment. It would be my advice to stop trying to time this test.
Exercise has some effect in eliminating EtOH from your system. Anything that increases your basic metabolic rate with have some effect, but nothing appreciable. For instance, it has been established that a good meal increases liver metabolism at a far greater rate than physical exercise. Vitamins seem to be of no detectable benefit. (Pawan, Ramchandani) This applies to EtOH metabolism. The direct effect on EtG is unknown.
Even before this test was introduced in the US it had been demonstrated that EtG was water soluble. (Dahl, 2002) The promoters marketed the test without properly disclosing that information, and with knowledge that the most widely used method employed to defeat a drug test is flushing. Even to this day that information is not disclosed to those paying for and relying on the test.
Will you pass the EtG test at 72 hours. Probably but there is also a chance that you won't. That is simply unpredictable nature of EtG and the flawed processes of the test itself. Pawan (1972) Ramchandani (2001) Dahl (2002)
