Yes, it will speed up the progress, but you must be careful not to fatigue the student. Too much time spent on these activities may frustrate the student, and that is not a way to help him succeed. If you are doing vision exercises, the eye muscles will get fatigued, and this will not help him do any better. It is just like when a leg muscle cramps. You would not want to keep exercising the muscle. You would want to give it a rest. Usually no more than an hour a day spent on the activities is recommended.
