isn't this akin, in effect, to successive over relaxation? https://en.wikipedia.org/wiki/Successive_over-relaxation

under-relax, converge real slowly

over-over-relax, oscillate

just-right-over-relax, get fast convergence

Its not quite the same. SOR is closer to coordinate descent in the way it acts
