Depends...
There are 2 types of martial art. I'll represent them mathematically.
Type 1:
This type has a specific counter for almost everything. Mathematically, its like saying x=2, y=4 and x=3, y=9, x=4, y=16 and so on.
Examples include Ju-Jitsu, Taekwondo, Karate, Judo, BJJ.
Type 2:
This time gives you the knowledge, and leaves you to get on with it. Mathematically, is like saying y=x^2 instead of giving a table of xs and ys.
Examples would be just about every single type of kungfu/wushu ever, shaolin, mizong, hongquan, jing wu, hung gar, and basically everything else.
