For example, when you do a cork 3 your goal is to match your flipping rotational inertia with your spinning rotational inertia, so that you complete one unit of cork rotation (360 deg) for every 360 deg unit of spin rotation. So you could simplify the situation to a solid sphere like the earth. What if the precession rotational inertia equaled the spinning rotational inertia of the earth? Imagine the earth trying to do a cork 3. For it to do so then for every small movement of a point on the equator of the the earth from west to east there would be an equal movement of that point either from north to south or from south to north depending on the right hand rule or whatever you do when combining two angular momenta. It would be as if the earth were simply spinning around an axis that went through 45 deg north and 45 deg south. There would be no precession, in the sense that there is no corking or wobbling of the primary axis of rotation.
same goes for a dub 7 or trip 10 or quad 14 or quint 18. Thats why when doing these combos you want to spread your legs/arms a little wider and crouch down to even out the spinning and flipping (corking) rotational speeds. Otherwise (for example) if you didnt crouch enough to increase your flipping axis angular velocity you would end up with something like a 1/2 cork 360 and land on your back, like a total bitch. Then the abominable snowman would catch you and you would get
