Breath sample acquisition introduces the largest source of variability in the measurement of breath alcohol. Sampling considerations, therefore, are very important when evaluating performance and interpreting results...in spite of instrumental sampling parameters, the operator's instructions and coaching efforts can still significantly influence replicate test agreement. - Rod Gullberg1

Breath test instrument manufacturers have done a poor job of overcoming the problem of sampling in breath alcohol.

They’ve programmed minimum parameters into their instruments, but the parameters are too broad and do not consider individual biological differences.
