Replot with node values off and then have a more careful look at the result. I can see a couple of odd features in the contour, but can't tell if it's important or not. 

A transient effect in a steady run will usually mean continuity residual hovers around 1e-2 or so. Generally the curve is fairly flat but noisy. RSM is always more difficult to converge, and generally also picks up any transient effects in the flow.Â
