Residuals in PimpleFoam

Hi all

I have a very basic question:
What is a typical residuals behaviour for a converging pimpleFoam solver?

I think my simulation converges (see attachment), since the final residuals of the simple-iterations continuously decrease.
However, the initial residuals of the PISO-algorithm remain at a high level...

Is this a typical behaviour?

Any experience on this is very welcome
Best, Triggin
