It comes up on the blog and well worth reading. It reports an ultra important precession in the opposite direction to Einstein’s GR and does not use dark matter to try to make a quick fix. The challenge now is to describe this retrograde precession with ECE2 relativity using all the means available: the lagrangian, hamiltonian and field equations with their use of the spin connection and also fluid gravitation theory. One of these field equations is the force equation (the one equivalent to the Coulomb Law). It is also usable for a binary pulsar. In my opinion we are making rapid progress.
