I see that you are very smart, but I want to challenge you on the idea of simplicity. That's the genious of it. You dismiss the lesson as too simple until you are ready for it. The white belt DOES see block punch, block punch, block punch... The black belt instructor sees "the basis of grading and instruction criteria." The martial artists sees a mantra, a moving mandela, a transmission not of block punch, but self actualization. Once a month, I go to a weapons class where I train with a pair of Professors. We were in a discussion of bunkai and they presented the standard explanation. I, being the wall-flower that I am, stated that I had problems with that and that I saw the move in such and such a manner... Professor asks me, "What rank are you?" I suspected, as usual, that I was going to be told to shut up (without words). I answered that I held xyz rank with our mutual head instructor for the system. "Well, if you're not coming up with some of this stuff on your own by now, then you're doing something wrong." So, I stand, ready, my valise, we, REAL men, don't call them purses, clutched in both hands in front of me as I await the bus. From the left corner of my eye comes movement and my right hand goes to my groin, my left to my head as my elbows come together protecting my centerline as I turn to meet my attacker, my left foot half-moon stepping in, my knee striking the inner thigh of my attacker disrupting his balance as my left hand arcs downward grabbing into the soft flesh of the inner thigh in a death grip as I step, again, thigh-to-thigh as Santiago would call it, and stepping behind the other foot of my attacker, I have the choice of pushing my opponent for distance or slamming him to the ground. I choose the latter. Now did I once mention block-punch? I practice chongi everyday. For REAL.
