I have these set in my 45 degree wall, and the difficulty can vary depending on how and where they are set. For example, I can’t sit start from these holds in that overhang, but can definitely use them much more easily as side pulls or bumps in a route. They are also nice on a volume in that setting. Holds vary in size and slightly in the depth of the incut. That being said, the V6 seems about right as in the description for most scenarios on a 45 to me, with them being easier on a volume and harder as sit start holds.
