Some will suggest a tighter range but I don't see the need. If it doesn't want to go there it won't and so far I haven't ever seen you have it go very high. Just because it is set at 20...doesn't mean it will go there and if it doesn't go there it becomes a moot point. The max setting doesn't do a thing unless it is ever reached anyway. You could set it for 100 cm if the machine would do it and if it never went above 12 then it doesn't matter what the max is set at.
Of course people can say...well if you don't need it why not just set it closer? Well it still doesn't change the way the machine works...if you set max at 14...and you never went past 12...it still works just the same way as if it was set to 20.
Limiting the maximum is useful if the machine was prone to chase leaks and in the past this was a real concern but with these newest technology machines they just don't go chasing leaks like the past generations of machines did. Your leaks are a non issue anyway.
Limiting the maximum is useful if pressure changes disturb sleep but if that happens you would want a much, much tighter range anyway...
Limiting the maximum is useful if higher pressures seem to cause worsening aerophagia...and then you have to compromise and probably use a much tighter range.
In your situation...the maximum setting really never becomes a factor...if you set the max to 12...it still would be a non issue unless you reached it and it's only an issue if it creates a problem. A non issue is a non issue no matter what the max is if you don't ever reach it.
I may have to RISE but I refuse to SHINE.
