Using TopologyVertices for BoundingBox

Hi so do I understand it correctly that the Bounding Box of a mesh that I create using a list of points is the same whether this list of points is mesh.Vertices or mesh.TopologyVerices?

Plus, is using TopologyVertices faster because of less points?

Yes. And even though TopologyVertices is less vertices, it (probably) does a lookup in the vertices array, making it slower overall.
