Well, for starters, how about the Word window size, whether the vertical ruler is showing, and so on.

Given how close Word's 'FitText' setting is to Acrobat's Ctrl-3 setting and the fact that the built-in options in both programs take account of all the variables, I do have to wonder why you'd even bother trying to second-guess what Acrobat will do via a Word macro...
