The usual entirely-true cliche is that most people on the postdoc-hiring committee will not themselves read beyond the first page or so of the whole thing, so you should be sure to make your big points, of course necessarily in rough terms, just on that first page From Mathoverflow
My ideal first page for a RS, I thought, should not be a dense text (maybe that is secondary, but it is not appealing), and so is to use for the document a 10 pt font size. I might be wrong. Should I really optimize it so that more statements fit there?
What if my most impressive result would be a graph?
