Pressure cooking for one?

I just got myself a pressure cooker, one of those modern ones with both "sautee inside the cooker" functions.

The problem is I'll be cooking pretty much for myself, and that most recipes I saw are for 4-6 people. The pressure cooker itself looks like it's meant to be used for no less than 1 portion.

My question is, would halving/thirding/quartering the recipe still be alright with these huge pressure cookers? I imagine with less water, the meats will be less likely to be covered fully, and things like that. Would the pressure just magically take care of everything, and cook things evenly?
