Project manager defines what documents will be an input for RST session. For example, it can be not only an artifact to restore but some background project information. It is recommended to give to reverse engineers number of words in original text so that they have an idea about amount of text they should get as a result: it can be one sentence or several pages of text. Though, the restored text may not contain the same number of words as original text nevertheless the values should be comparable.
