When sitting on a saddle should the saddle "encompass" the sit bones or should the saddle "rise up" between the sit bones. In otherwords, with a proper fit, should the sit bones be in the center of the saddle "padding" or should the sit bones be to the outside of the saddle "padding" sort of wedging up in between the sit bones.??

I'm guessing the bones should be centered on the padding but I honestly don't know.
