Because I've tried to do it other ways, how much explanation do you want? The wa you are doing it is adequate and is the best way to train you ditto because it involves the least amount of work and does not take time from your day, however you can do t another way if you enjoy working your rear end off to come to the same outcome as you would have had you conitnued to do it the way you had been. Are there any other ways? yes. are there any other easyier ways? no.
