InDesign CS2 para count whackiness

Last night I was making a paragraph counting script. I was using two ways to count paragraphs in a long word file newly placed in a new document (i.e., no modifications, the whole story is in linked text frames).

If I selected the first text frame and got the contents of the parent story and counted paragraphs, the total was about 100 paragraphs higher than if I selected the whole story and counted the paragraphs of the SELECTION (making sure everything was selected).

Anybody know why there is such a disparity. From what I read in the ID CS2 scripting docs, both should count only hard returns as “paragraphs.”

Any ideas? Many thanks. BF
