My sifu noted that with Chinese martial arts: “If you miss a day, you regress a week. If you miss a week, you regress a month. If you miss a month, you regress three months.” This was something he was told by his sifu, and he claims that non-Chinese styles are not like that. Since his background includes training in two different styles of Karate, Hung Gar, and Wing Chun, he has some means of comparison. With Wing Chun, the details are all in the subtleties, as well as in building contact reflexes, so I can see how that might be. I know that when I took a three week hiatus, it certainly felt like starting over.
