Some Reasons why I, Brian Manzella, don't improve 100% of my students.
• Not enough time with the student, and (or) not over a long enough period of time.
• The student doesn't apply more than about 10% of what they were taught.
• I gave them the wrong information, or what I gave them was at the wrong time for them, or I communictaed it to them in a way that was not the best for the student. In other words—Teacher Error.
• The student won't even check their grip in the manner I show/explain/teach them to. In other words—The Student doesn't even "show up," or won't "show up."
• Everything went fine, but the student jsut wanted to do it "their way," or some other way. In other words—I like Cadillacs, they want a Buick.
• Everything went fine, but in the mean time, someone else told them: "That guy doesn't know what he is doing, you need to go to so-and-so." In other words—I was Sabotaged.
Other than these senarios, I improve about 97.5% of all my students.
