Maybe you can't ... it works for me ... I'm able to avoid the attack. Afterall is said and done, I need to avoid the attack and counter. If I need to step back to 7:30, I do it. If I need to step to 9:00, I do that. Our style does not state that a technique MUST be done this way!!!
Our philosophy is to teach it the way we were taught and encourage the practitioner, with the help of the instructor, to experiment with what works and what doesn't dependent upon the attack, its speed, power and angle of attack, whether it is a punch (right, left or combination), a kick, a push, whatever. Find what works and what doesn't. We realize that there isn't going to be someone there, at an altercation, to yell numbers at us, we will need to simply do what comes to us, without thinking. I react to the situation, if I step to 7:30 and deliever a strike to the knee and that stops my adversary, you won't see me complaining that I stepped rather than pivoted. You will see me removing myself from further incident.
Either way, it's all #7. The concept, as I see it, it to avoid an attack and counter with a linear kick.
