I have a conundrum. I have studied Tracy's Kenpo under Kudan Ernest McPeek for several years. I moved on after reaching Ikkyu (first brown). Looking through the boards here, I see several discussions of techniques, yet the technique described does not match up with what I know... Take for example this discussion of Leveling the Clouds. The Leveling the Clouds we were taught has the same step and block, but then we skip right to the elbow break, then switch hands, step back pulling into a left elbow to the face... I don't remember there being a A, B, C, or what-have-you. So I guess the question is, how much local variation is there allowed in curriculum? Does a school operator maybe get to set their preference for what variation is taught as the baseline? or perhaps even outright change entire techniques? I have nothing but respect and distinction for what I have been taught, I was just wondering whether this is common, or I am on the outside looking in?
