Oracle 452 Mask Users: pressure change needed?

I have a new Oracle 452 oral mask on trial to replace my P10 nasal pillows.
Early returns are that it is likely to reduce my Large Leak rate to zero.

My question to experienced Oracle users is: did you find it necessary
to change your pressure settings from your previous mask?

Up or down?

And BTW, what mask setting do you use on your CPAP?
It isn't listed on the user guide or any of the several likely places I've checked.

Thanks for your response!

I never changed any settings. But I do use a range. I don't know if my typical pressures were the same or not. Just that it handled it just fine.
