Are these leaks significant?

Does anyone know if I should be concerned about any of these leaks shown and whether or not you may tell if I am mouth breathing or losing my pillow seal?

They are NOT significant leaks.
Your machine reports total leak. See my SleepyHead tutorial for detailed explanation of leak and understanding it.
Link to the tutorial is in my signature line and there's also a thread in the very top of the announcements box on the forum main page.
SleepyHead can make mountains out of mole hills due to the scale involved and that's what has happened in your report here.

Total leak (expected vent/intentional leak plus any excess leak) will vary with the pressures...more pressure means more vent/intentional leak so that top leak line will go up when the pressure increases even if there was zero excess leak.

Large leak territory for your machine is going to be up around 80 to 90 L/min..most likely 90 L/min and you never even come close to it on this report. The machine can do a good job compensating for leaks up until what it calls Large leak territory. The most recent version of Sleepyhead actually will flag large leak if it happens like Encore does.
You wouldn't get a large leak flag with this report though.

Now if these smaller leaks wake you up..they need to be worked on but because they disturbed your sleep and not because they negatively impacted the pressure therapy.

Thank you once again. I will print your pointers out because I like reading paper printed material. I believe it retains information in the brain better
