!. How long do most of you find it takes with your students(or yourselves) to make a MECHANICAL change?
2. Do you find this time varies if the student is making more than one mechanical change, or stays about the same?
3. How long before the student is able to take the change(or changes) to the course, and do better than with his former technique?
4. Have you found that a specific number of repetitions per practice session is necessary to cause the change?
5. Have you found that going beyond a certain number of repetitions, or certain amount of time per session is counter-productive?
In general, as probably most of you have noticed also, if the initial change or changes cause the student to immediately produce better shots, he will take to the changes fairly quickly. However, how long it takes for the change, or changes to become part of his standard technique, is another thing.
