You should include any grout line and try to make it uniform. You may not have used grout in your previous project, but for a "stone effect", you may want a fixed (1cm?) grout line around all pavers, but not necessarily along the edges.

(No, I am not trying to add a mathematical complication, just a nicer appearance.)
