When training fine motor skills, are identically setup practice sessions ideal or, like machine learning, does adding noise/variability to the practice session increase skill acquisition?

According to "Motor Skills Are Strengthened through Reconsolidation" (available through SciHub) adding variability to practice sessions increases learning speed. In the paper, patients were directed to move a cursor on a screen to certain targets via pinch force. Patients who's pinch force mapping was modified during each trial ended up learning faster and performing better on the original pinch task.
