As I understand it, correct me if I'm wrong, this constant is a unit of expansion for Mps distances based on the red shift formula. Any use of it in smaller parts, even lys or km is outside the limit of its purpose. If other words the farther away it is, the more additional expansion needs to be applied. To see this in terms of trillions of parts where parts are less that a trillionth of a Mps, for instance, IS infintesimal and not appropriate for the constant's purpose. Yes, I like your argument for the small expansion rate. But when considered in all directions it isn't so puny to me. Thank you for bearing with my learning curve and best wishes in the success of your model.
