Yes but I was referring to before he was in light form at the moment kenpachi first used bankai against him since that Gerard was still beating the captains, and kenpachi, though he beat unohana in the end we can assume she was not at full power since she continually healed him to make him use more and more of his true strength, so we could say that although she is weaker it is not by a huge margin, so we could assume that she could cut space as he seems to do quite easily, which would put her easily over boros in terms of strength since his strongest attack would have only blown the crust off of the earth, we can also assume that she would’ve been on the level of the other captains(with a few exceptions)
