I have a small mooncup and I'm considering getting a small lunette. I know that measured to the holes lunette has a higher capacity. But in use is the difference noticeable? I'm not sure how accurate 'to the holes' measurements are in determining when the cup will overflow. I'm sure it's fine to be used as a rough guide, but there are bound to be other things that decrease the capacity, such as the cup sitting at a slight tilt inside you, muscles squeezing the cup a little bit, fluid making the cup heavier etc.
So I'm just looking for experiences really. If you've used both do you notice a difference in how often you need to empty?
Or does anyone have any general opinions/experiences on how accurate 'to the holes' is in practice?
