You are forcing me to exercise my gray matter, but how about this...
What happens if the machine figures in minutes and reports in hours.
Initially, you have 5.6 hours = 336 minutes. If you had 100 apnea/hypopnea events during that time, you would end up with 100/336 = 0.297619 as an AHI, which rounded up would be 0.3.
In the second case you have 6 hours = 360 minutes. If you had 144 apnea/hypopnea events during that time you would end up with 144/360 = 0.4, with no rounding needed.
What do you think about that?
