Which mask setting should I choose?

I asked this on my post about "Questions about the Innomed Hybrid mask", but I was afraid no one would check it and I want to use it tonight.
I got this mask today and I'm not sure which mask setting I should choose for it. Any ideas? Its presently on Swift, but I'm sure that's not right.
Thanks.

Use Mir Full. Mir Full is what is used for the Quattro and Ultra Mirage full face mask. The hybrid flows at a higher rate. So the LCD display on your machine will display a higher leak rate than you would normally see. To find out what is acceptable do the following:

Check out this web site for comparison of flow rates.
http://www.internetage.com/cpapinfo/leak-rates-1.html

-Subtract the flow rate for the hybrid from the flow rate for the Ultra Mirage full face mask for your pressure setting.
-The difference is in lt/min. Your machine shows the leak rate as lt/sec. Therefore divide by 60.
-Subtract this number from the leak rate result shown on your LCD screen.
-Resmed states that less than 0.4 lt/sec is an acceptable leak rate.

Humm did I get the math right..

Thanks Ms. Snuffy.
