It's pretty standard for latex to add a little whitespace between captions, figures etc to reduce the chance of page breaks mid-paragraph. In some cases I feel latex is a little too liberal with its stretching. This may contribute to the length of my document too.
I'd like some control over the threshold of the decision to page break mid-paragraph or stretch, similarly to the way
\emergencystretch can be adjusted for whitespace within a line. Is this possible?
Perhaps penalties is what I'm after, but I haven't got anything working so far.
