There's some weirdness in the calculation.
The air reduction has to be more than x%, but the length of the apnea is measured for a time period when the airflow reduction is somewhat less. Sometimes this cause the duration reported to be higher than you think it is.
Also, if you take a few deep breaths before the apnea, the baseline the apnea is measured against may shift.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
