In order to determine what Verbum is actually showing me, when the documentation lacks specificity I often run a guide on Gen-Rev to get a sense of all the resources being scanned for results. When I do this on the Textual Variants section, Verbum "forgets" to include Online Manuscripts which occur only for the New Testament. It does include it if I request Matthew- Revelation but not for Psalm 151-Revelation. It should check if any portion of the range is in the New Testament before excluding the section.
