Pre processing progress

I am trying to understand how to best visualize and see the current status of my pre-processing (both S1 and S1) for a site.
What I am more specifically thinking is if there is any way to know how far off real time I am with my pre-processing.

An example. Lets say i start a site today with a date range from March 1, 2021 until December 31, 2021. Is there a way to see how far behind current date my pre-processing is and how much there is left until I have fully catched up to something close to real time pre-processing?

I hope I managed to make this clear.

Thank you for your input.

Best Regards
