i use it for kick sets this way i don't have to strain my neck when head is up/down. for me its just for comfort.
As far as lung capacity goes, i try to include swim with no breathers one lenght (25m in my case) and breadth control is also important.
I swim freestyle so i do alternatin evry 3 strokes but often i do every 4 strokes - often feel like i am about to burst but already can feel the results.
