Default Best parameter for GCI mesh independence study?

I am modelling flow over a backward facing step, as shown in the attached image.

I am unsure of what parameter to use for a GCI study.

I first thought of using the maximum pressure, but this value does not seem to converge to anything, even when the mesh is really fine.

I also thought about using the reattachment length, but the exact value of this seems to be vague.

Any suggestions will be greatly appreciated.

Thanks in advance
