How accurate is Genetic Phylogenetic Bracketing?

Bracketing is a tool, (not the only one) . It especially is driven by fossil "features". Newest thinking is much more genetics inclusive. I can see a "backward bracketing" from species we can assure are derived via genetic relationships nd see where they appear with their "fossil relatives"> remember that the Hyrax was never considered as a cladistics relative to the modern elephant and its group also included other small mammals of a non-elephantine type.
