How to tell if leak is from mouth or mask?

[AirSign]

In some other posts, I see that it seems to be possible to know from Sleepyhead reports whether Large Leaks are coming from mouth leaks, or from mask leaks?

Is that possible?
If so, what data should I look at to know what the source is of Large Leaks?

TIA

First of all, decide if it's really a problem one way or the other. Look at your pressure graph where it shows LL for large leaks. Is it consistent throughout the night? If so, suspect mouthie. If only on occasion, suspect mask. But mostly, if its not a predominant feature of your graph, you're good to go regardless.

Normally if you are mouth leaking you will have more dry mouth issues as the air escapes through your mouth.

I don't use SH, not sure how SH work out large leak but according to ResMed leak is acceptable and considered good if 70th percentile leak is less than 24 L/m but again any leak whether large or small affecting your sleep, need to be sort it out

As for how to identify mouth leak, dry mouth is the first sign and leak graph shows few spikes at some of the times and none at other times
