Ludwig's WRAP-UP
In summary, while "as per control" is grammatically acceptable, Ludwig AI indicates it's not commonly used and may sound awkward without clear context. It functions as a prepositional phrase to indicate adherence to a specific control or guideline and is generally used in formal, often scientific, contexts. For clearer communication, it's best to specify the control being referenced or opt for alternatives like "in accordance with" or "according to regulations". The lack of real-world examples suggests it's best to use more direct and specific phrasing.
