Muscle memory and reps...How many?

I have read many articles by Hock.  I dont always agree with him, but I beleive he is on-target with this article:

 

by W. Hock Hochheim

"In Motor Learning, Dr. Schmidt states with a flurry of charts and studies that it requires approximately 300-500 repetitions to develop a new motor pattern. Conversely, once bad or inadequate habits are already in place, he states it takes about 3000-5000 repetitions to erase and correct a bad motor pattern. Layman readers and regurgitators please take note, 300 to 500 repetitions, not thousands. Hundreds. For some reason, many trainers and writers have latched on to a reverse misunderstanding of this study..." for the full article, follow the link: http://www.hockscqc.com/articles/howmanyreps/?index.htm
