leak numbers question

Hi, I have a Luna 3b auto with humidifier and rested n30i nasal mask on my machine the read out reads 2.0 LPM for leakage. When I download ,app on my phone says (>90LPM) is 00:52
I'm confused about the difference in numbers... TIA
my overall #s compliance =8:18 P95 (cmH2O)=8.5 Mean pressure (cmH2O)=8.0 AHI=2.0 CAI=1.0 LEAK TIME (>90LPM) =00:52

Read out on machine says leak time 2.0 ?

I'm not familiar with your machine, but I bet the read-out on your machine is giving you an average for the night. The app on your phone is telling you you spend a little less than one minute of the night with leaks over 90. Make sense?

Thanks for reply... I was thinking 2.0 was a good number and yes I thought 00:52 was total time.. If I have a bathroom call during the night I do not shut machine off... I will try shutting it down to see if that number changes...
