I have a different Intellectual Departure in the ideal phase. After discussing it with Mr. Contatser, I decided to leave the back knuckle strike in, even though it was not part of the original technique. So as you read it, remember to delete #3.
11. INTELLECTUAL DEPARTURE (front- right front thrusting ball kick)
1. With your feet together step back with your left foot toward 4:30 into a right reverse bow stance (to move out of the Line of Attack), while simultaneously executing a right inside downward diagonal block - palm down, against the inside of your opponent's right kicking leg. Your left hand checks at your right shoulder.
2. Without hesitation and while still in your right reverse bow, execute a right upward stiff leg kick to the opponent's groin.
3. As you plant your right foot down to point of origin, execute a right outward back knuckle strike to the opponent's temple, utilizing rotation, body momentum, gravitational marriage, and borrowed force.
4. Immediately drag step shuffle, gauging the appropriate range, and execute a right snapping knife edge kick to the inside of the left knee.
Of note: if you delete the reverse bow and utilize the reverse kneel or cat, you lose the residual torque for the lifting kick. It allows more flexibility for a rear kick instead, but that is not the way I saw it executed, although I do both sparring. This lifting kick from the reverse bow is a sneaky little hard kick to the groin, that does not explode from the ground, until you get tension through the hips that has to be released via the lifting kick.
You can always modify the stance and use a reverse close kneel or cat, or change the kick from lifting to a back kick or rear scoop (depending on range), but the technique as written above, minus the backfist, was what I used to see, and was verified by Mr. Conatser as the correct wording. Take it for what it's worth. It has some other principles and concepts, and utilizing this kick avoids violation of point of origin, economy of motion (which might be why it was done this way), and the technique itself teaches residual torque, stepping off the line of attack, checking, borrowed force, rotation, body momentum, controlling opponent's height-width-depth zones, minimizing angles of entry to your own vulnerable targets etc., etc., etc.
