If you are talking about doing calibration control runs on measuring equipment, I completely agree. Those should be done before every run for critical data and afterwards also to demonstrate that the calibration didn't shift during the run.

If you are talking about process outputs for an R&D situation. Once you have established a baseline against which you are measuring improvements there is no need for control runs.

Each process run is compared to the previous runs. It is either better, the same, or worse. No additional control runs required.
