It is hard to say. For correct cross-references, two runs are usually enough. But there are some cases regarding tables, where even more runs than three are necessary - the same number as number of columns is needed. But I don't remember what feature it was, and I cannot reproduce it now. But anyway, when you don't add new sections, cross-refs, etc., one compilation is enough. Best regards, Michal
