The mouth-fill is best practiced with a buddy in 15m of water. One mouthful at the surface should get you to 15m when using a mask. Whatever depth you get to, you can then compute your max depth based on your mouth-fill depth. For example, if you can fill your mouth at the surface (1 atm) and make it to 15m (2.5atm) with a mask, then you can reach two and a half times your fill pressure.

To 15m with empty lungs? Or do you have air in your lungs, just closed throat and air-filled mouth?
