Basic blaster blocking comes as part of Shii Cho.
Ch'lana was not big on rigorous memorization of specific zones and such. He taught forms, attacks, but did not really give them names. High strike left, high strike right. Low block left, low block right, that sort of thing. You've formalized a lot of what Ch'lana would have taught, given it names and categories. The same basic concepts, but you've formalized it.
Ch'lanan taught my example. If he managed to tag Collan in Zone 4, Ch'lana would show him a block for that specific attack, for example. He's much less concerned with rigorous repetition and more concerned with you guys learning how to do basic attacks and blocks.
