Default p residual too high but converged - backwardFacingStep2D

Hello, thank you for any help you could give me.
I am new to OpenFoam and CFD in general and I'm studying the backwardFacingStep2D in the tutorials, using kOmegaSST.


I want to know if my solution is converged but when I plot the residuals using pyFoamPlotRunner, I find that the residual for p is too high. What do you think?




The geometry is rather simple and I did not change anything for the tutorial case so I'm guessing the solution is in fact converged, so how to explain this high residual? Is it okay?

I am using the GAMG solver for p with a tolerance of 1e-10.


Thank you for your time and have a good day.
